I tend to approach it with the mindset of "What if it's that hidden gem and I truly love it?" I've watched all kinds of movies, some pure dreck, with that in mind and, while it's infrequent, do occasionally find those little gems of films I never thought I'd enjoy, much less want to see again. Is it worth it? Not sure. But I also love movies and don't consider watching even "bad" ones total wastes of time. But I do get where you're coming from. I don't particularly care for movies about criminals and gangsters outside the noirs of the 30s/40s. I *do* tend to enjoy war movies from just about any era. However, I find some of the ones of the Vietnam era tough viewings. It was a very troubling time in many ways.
