Alien [ imdb ] was probably my biggest error. I was so afraid of being afraid of the movie that it took me years to see that one as well. It's a hell of a science fiction movie, one of the best in the history of cinema, and I can't believe I deprived myself of that experience either in the original theatrical release, and for years after.
What I wish I could understand today, prior to the advantage of hindsight, is which movies I blew off or ignored, that I would regret having done so upon seeing them. Honestly, my life would have been just fine if I'd never gotten around to seeing The Karate Kid, but if I'd never seen Alien, I would be much the poorer for it.
Do you share this tic of mine, or some equivalent of your own?
What movies (or books) did you ignore and avoid, only to realize your error later?
What overlooked movies (or books) would you urge me to pay attention to?
