This is one of those to rewatch one day as I only saw it once or twice when I was a kid. However there are just so many movies I still have to catch up with that it gets pushed back. One day though, I will rewatch this classic for sure and I don't think it will ruin a good memory as it's one of those that stands the test of time.
RE: Back To The Future (1985) Is One of My Favorite Films Ever. Nearly Forty Years Later, It’s Still as Fun, Smart, and Rewatchable as the First Time.
