The product is cool, the only issue I had is that one of the magnets (the one for the flying skateboard) didn't work. Also, because I opened the box late, I was not able to request a change, my bad. Despite that, everything is great and you can have fun.Great Scott! This is a must if you are a fan of the BTTF films. Period. However, if you kinda like the movies but are mainly buying it for the game play or the character abilities, you should read below first.PROS:1. Marty MinifigThe Marty minifig is a great addition to a collection if you collect minifigures. He also has the sonic shatter ability.2. DeloreanThis is easily the top reason to buy this set. Once upgraded you can do silver block blow-up, it can fly, it has a flying cargo ability, and it can access the time portals around the BTTF adventure world. The abilities on this car make it very useful throughout the main game and also in other adventure world packs.3. Adventure World The included adventure world is really fun, although kinda small. The reason it is so small in size compared to others is that it centers around the clock tower. You will find 2 different time portals that the Delorean can get on that will take you to the Old West version of Hill Valley or the Futuristic version of Hill Valley. If you change something in the past, you will see certain things change in the future, which is a fun feature.CONS:1. Level PackThe only con of this set for me is that the extra "level pack" section you get is VERY short. It maybe took me 20 minutes to beat. And it doesn't have much replay-ability. It doesn't give you the whole movie like the Ghostbusters level pack does. It really speeds through everything and doesn't spend much time on the story-line. I was pretty disappointed in this part of the game, but as a HUGE fan of this film, I would have bought it even if it didn't include the extra levels.2. HoverboardI think it's fun that they included the iconic hoverboard from the series. However, I don't use it at all. It lets characters hover above the ground and move a little faster than walking, and can be upgraded to fly, but I find that I never use it in game.So, if you are a fan of the films you'll want to get it like I did just to get the figures and the adventure world to play one of your favorite movies. If you are thinking about this pack vs another, like Portal, or Dr. Who, you may want to go with one of those instead for the longer levels.I am torn between a 4 and 5 star rating on this one (wish I could give it a 4.5). The Level itself is pretty basic and a little on the short side... although there is a secret room that I really loved them including that I found on my second play-through (not saying more because of "SPOILERS"). The dialogue with Marty and Doc are really good though, as is the clever ways Lego retells the story. What really redeems this one is that the Hub world is my favorite of all the Hub worlds. It is mainly because you go back and forth in time through the 3 time periods and the things you do in the past sometimes effect the future, and so it is cool to go through all three time periods in order to complete a task... plus the charging the DeLorean up and it zooming off into the future (or past) with the epic woosh and the theme music playing on reentry is pretty cool!As far as the character/ vehicles go, Marty is useful for his ability to use Sonar smash (otherwise you would have to pull out a vehicle like the Batmobile upgrade each time) or buy another character specifically for that. Other than that he is pretty basic and unimpressive. The hoverboard really is useless outside of the couple in level tasks that require its use... (just a point for nostalgia... although I must say it is cool that it doesn't work on water in the first build, but in the builds with "POWER" it does work on water). Sure it can fly, but so can the DeLorean and the DeLorean flies better and does more stuff.The DeLorean, on the other hand, is one of the BEST vehicles in the game, and makes this pack well worth it! It is my favorite vehicle for completing races (both flying and on the ground). It converts from a standard vehicle into a hover vehicle, so it is useful on both levels... I hardly ever use the Batmobile now and the Tardis has to share its time with the DeLorean (it's also funny how the Doctor says, "it would take forever for this vehicle to get up to 88mph" (or something like that).Part of me so wants to give this a 5 star rating, but the Level itself was just too unimpressive. I would definitely highly recommend it for the DeLorean and the Hub World though.I'll admit I haven't played the bonus level yet, but I really initially just got the pack for Marty McFly. He does not disappoint. While his fighting/smashing isn't as great as someone like Batman (who, in my opinion, is the best fighter in the game), the way they incorporated the use of his guitar and the animation that goes along with it is sure to please fans of the film franchise. And they even got Michael J. Fox and Christopher Lloyd to reprise their roles!This pack also gives you access to the Back to the Future dimension, which is 1980s Hill Valley from the first film. I think you can time travel once the Delorean is built, but you have to play the bonus level included with the pack to get instructions for that. Still, until Doc Brown is released in a later fun pack, this is your only option into this world. Either way, as you rip through the portal and The Power of Love starts playing as you look down at Hill Valley from atop a building, you can't help but smile and think it was well worth the money.Our 5 year old boy and his 3 year old brother love the Lego dimensions sets, both playing the game on the xbox and also playing with the mini figures outside of the game so we get a bit extra value out of them. I grabbed this back to the future level pack when it went on sale recently.I wish the price of the packs was lower, there's such a huge array of them and at the regular price it's quite an investment to keep up with to unlock stuff in the game.My advice is wait until there's a sale on Dimensions sets, seems to happen every couple of months so wait and grab some when they're reduced, or otherwise look at the fun packs as they're the best value way of unlocking extra worlds in the game.Hope that helps!I don't play the game, but luckily you can find the assembly instructions on YouTube, so you don't have to! The hoverboard is way, way more complicated than it needs to be, but the Delorean mini-kit is spot on and a lot of fun to put together. Wish this was around when I was actually a kid so I could have had the imagination to play with it rather than leave it on a shelf.Lego siempre se ha caracterizado por darnos productos de calidad, que aunque esperaba que las figuras fueran un poco mayores, su funcion cumple al 100 tanto para el juego o solo para coleccionar, recomendado para los fans de volver al futuro.This level is cool if you liked the Back to the Future movies. The level is only about the first movie, not the two following ones. The level is also pretty short (15 minutes) ... It takes more time to build the toys than to play the game.It's a bit on the short side- we finished it sooner than we would have liked- but still a great Dimensions adventure. It was really cool to follow Marty on his adventures through time.
