bttf 2 is the best of the 2 sequels, although bttf 3 isn't at all bad, whereas bttf 1 surpasses them both as it sets the story. however, whereas individually they may have their faults, as a trilogy they are incredible. btff 2 gave kids (i was only 6 when i first saw it) hopes of a future with flying cars and hovering skateboards, which was excellent. and the whole trilogy made me want to buy a delorean, but that's just because i'm easily influenced by brilliant films (and their equally good sequels). so buy this now (and while you're here, buy the other two- it works better watched as a trilogy rather than a single film) 5 stars!
