Well, it depends on your taste in movies. I watched Kiss Kiss Bang Bang a couple of month ago at a festival and nearly peed myself 'cause I was laughing so much.

I'm not much of a Val Kilmer fan either but his character was probably the least cliched gay character in a movie ever and he pulled it of beautifully. Plus they poke a lot of fun at the Hollywood movie industry.

Basically, if you liked stuff like the Lethal Weapon movies, chances are good that you'd enjoy this.
