I watched since season 1 episode 'House of the Rising Sun', got addicted, was disappointed at how season 2 ended, and thought that it 'jumped the shark' in season 3, although I kept watching. Then there was the writer's strike and an abbreviated season 4, most of which I missed because of watching primary season.
Don't know what the hell is going on now, but I'm watching. Just my dogs, myself, a couple of hard apple ciders, munchies, vapor and maybe g/f will come over and watch.
I own the season box sets and maybe some day I'll watch it in one go.
But it's very depressing when they kill your 2 favourite characters in the first 2 seasons and then start killing your remaining favourite characters on an almost regular basis.
