There is no way that a remake can be any better than what we saw in the original movie and its two sequels (okay, the third part wasn't so great, but I'll play along).
I really hope this doesn't turn into something because I love BTTF.
And I know I'll end up disliking a re-imagining of it.
With that said - it sure would be intriguing to see if they have it set in the current day and the hero has to go back to the 1980s.
Okay, I should stop there before I start thinking more...
