Why are movie trailers so awesome?

I love watching movie trailers. I check the apple website every day like I check my emails, eagerly looking for new nuggets of pleasure. I think I like trailers better than actual movies. Less of a commitment. Plus apple often has ones up of these kind of obscure independent flicks that don't play in most movie theaters. I have absolutely no desire to see this one but the trailer's kind of fun. And sometimes they have featurettes, which are cool too. The featurette for Gentleman Broncos isn't that funny, but worth watching I suppose. I wish more thing could be made into trailers, like recipes for dinner. That would be fun.
