There's nothing wrong with enjoying a bad film. Braveheart was Gibson's first attempt at cinematic masturbation, a technique he later perfected with The Patriot, but it's still a fun movie to watch, because it has some great battle scenes, some decent humor, and a couple of supporting actors (especially James Cosmo and David O'Hara) who far outshine the star. When Braveheart shows up on TV, I will stop flipping channels and watch it, because I enjoy the hell out of it. I just realize that I'm enjoying it the way you might enjoy a bag of Doritos. It does it's thing, but Apollo 13 was clearly the filet mignon that year.
Now, Gladiator. I can't even justify that one. That movie was just an abortion. Shouldn't have even been nominated.
