"So, a Back to the Future adventure game, huh? Doesn't sound all that great. I mean, the movies had a very unique feel to them, and it's not like these guys would be able to recapture th-" Yeah, I'm just gonna cut you off now, because this is very much the Back to the Future you (most likely) cherish, and very much as enjoyable as the movies. It's the perfect sequel, made better by the fact that it's longer (5 episodes clocking it at 2-3 hours each) and in video game form. Indeed, only through a video game could the feel of the movies have been pulled off so well; fresh and different, but familiar and fitting. It's not one of those super-hard, inaccessible old school adventure games, either: pretty much anyone can play through this no problem, and puzzles are in almost all cases very logical and require thinking as opposed to random luck.
If you like Back to the Future, you should play this whether you like adventure games or not.
