Mr. DuLac’s review published on Letterboxd:
Roads? Where we're going, we don't need roads.
It's a problematic sequel that doesn't get better with repeat viewing, but I still love it. I think it's that I don't particularly enjoy the trek to 2015 or the Faux 1985, but you have to go through those two to get to the highly enjoyable third act that takes place in 1955.
Now I might be wrong, but I'm pretty sure that the sequel creates a plot hole, or paradox where it goes completely against the "time travel rules" that were set up in the first film. Not only that but they actually fall back on those same rules after they were clearly broken. Also is it just me or does traveling to the future to prevent something from happening make very little sense? Either way... doesn't matter at this point, but I do wonder what type of sequel we would have ended up with if they hadn't painted themselves in a corner with the ending of the first film.
As convoluted as it is with plot holes and all, you still get the characters you loved in the first film true to form. Except for Crispin Glover damn it! I still love this film though, flaws and all. And we better get those cool Pepsi bottles in 2015 too.
