Why It's Awesome: Time travel films are a dime a dozen and so few of them have any sort of functioning internal logic, yet that's just one of the many reasons that, conversely, Robert Zemeckis' classic sci-fi adventure film has endured for three decades.

There's so much packed into this movie: the hilarious scenario of a young man getting to hang out with his own parents back in their high school days, the 50s style, Huey Lewis and the News, the DeLorean acting as a time machine, the outrageous time travel jokes (the Ronald Reagan gag is a killer), Christopher Lloyd's insane performance, and the fantastically charming work of Michael J. Fox as protagonist Marty McFly.

It's a wonderful feel-good film that's nevertheless extremely smart and prone to a few moments of edge that younger viewers will likely miss (and be shocked at when they revisit it a few years later), ultimately spawning two inferior but tremendously enjoyable sequels.
