I'm one of those people who likes really bad movies almost more than I like the good ones. Have you seen "Glitter"? It makes "Showgirls" look like "Citizen Kane."
I saw Jaws 3, and found myself laughing out loud. Thankfully, I was at home, watching it on TV. I laughed hysterically when I saw "The Day After Tomorrow" in the theater, and some people behind me asked me to shut up. Whoops!
