Pet peeve warning:
I hate it when a television show has characters who are supposed to be surfers. I don't mind if they throw it in as dialogue or whatever, but when they actually set a scene in the water and the actors look like they've been air-lifted onto the board and balanced there, it's really distracting.
Last night, I was watching Veronica Mars (which is a really great show, don't laugh!) and the brooding bad-ass rich kid Logan seemed a lot less brooding and whole lot less bad-ass when he was chatting with his friend while floating in the water in a shiny new wetsuit on a cheap-looking longboard. They were both sitting in the middle of the board so it was flat on the water. They looked like they would tip over if they had to try to raise the nose of the board out of the water to turn around should it occur to them to paddle for a wave.
It's like when you watch people who don't know how to play guitar, play guitar in the movies... takes you right out of the scene.
Good surfing scene on TV? Simon Baker in the premiere of "Smith" (which is cancelled, but that setting was GREAT). Baker, tanned, in boardshorts, cutting up a wave on a shortboard. (It helps that he can actually surf.) He trots to shore smiling and full of aloha spirit. He greets a couple hard-edge locals who give him a hard time. He backs off, but then kills them with single shots to the head from his sniper rifle. Every surfer's fantasy for dealing with aggro meat-heads.
