Terrible thing to say, but I seldom if ever watch a film I don't think I'm going to enjoy, and if I'm not enjoying it, I switch it off and never go back to it!

Films I had to watch for Film Studies were, of course, different, but I have no intention of revisiting 'Now Voyager' or 'The Searchers', or 'Soldier Blue' because I didn't like them. In all fairness, I have so much else going on that films are only a small part of my spectrum of interests!
