All right, who was the dirty rat who put me on to Castle? Not only am I going to have to watch all of Season 1, there will be at least four more seasons that I'll be bound to buy. And who knows what will happen if ABC doesn't have the sense to drop Castle after Season 5?Hi, my name is Gunnar, and I'm a TV show junkie... (Ok, not quite as bad as Pete, maybe, but that's not much of a consolation )
