First one is a perfect movie. Not a single thing to change that could improve it. Accomplishes everything it sets out to do. I can’t think of a single movie that is more fun this one.
Second two rehash jokes from the original and exist solely on its coattails. The fact that some people argue that they are actually decent movies only proves how incredible the first one was. And the fact that I still watch them from time to time proves that no one, not even a curmudgeon like me, can resist Marty and his wacky adventure to 1955.
P.S. If they existed, I’m not sure I’d even want a hoverboard. I mean, I’d take one and ride it for a few hundred hours, but they’re so overrated.
