Well, my fave extreme fishing program is Extreme Fishing with Robson Greene. He's a Geordie actor/singer who loves fishing and the programmes all have him going around the world catching (or failing to catch) all sorts of fish. And he's really, really enthusiastic about it all!
Some of the full programs are on youtube I've linked to the 1st episode of season 3 - I think the earlier series were better, but I couldn't see them there.
