What makes a movie good?

A movie needs to understand it's place in order to be good. Movies like "Freddy vs Jason" can get away with gratuitous plot holes because they're campy. Nobody goes to "Freddy vs Jason" expecting a riveting plot. Movies like "Underworld" however sell themselves as being serious and should be taken seriously. So, when a movie like that has cruise liner sized plot holes, it kills the entire experience. This is just one example, however. If you're gonna be campy, be campy. But if you're going to be serious, then for the love of God don't glaze over things like "plot" and "character interaction."

Another good example would be the movie Signs. This movie was played up so much and I never saw it in theaters, so when it came out on dvd I bought it trusting my friends weren't complete morons. FULL of plot holes, two good examples are the fact that the aliens could jump onto the roof of a house, but I'll be damned if they can kick down a wooden door. Oh, and their weakness is water, tell me how all the water vapor that is naturally in the air didn't kill them? After this movie ended I wanted to break it into a million pieces and cut the directors throat with one.
