Are you a big fan? Are they planning on releasing another one, or a re-make?
Somehow, after the first Back to the Future (which I *loved* and watched in the theatres and rented a gajillion times as a young teen) I didn't really follow the series.
But those BTTF sequels always seem to be on TV when I'm traveling in Europe! I think I've watched the entire series in German at least three times.
For me, classic scifi authors like Ray Bradbury have always seemed way more on point in their future world-building.
It would be fun to compare a bunch of different book and film visions, actually.
