Agree on Mrerlin but the difference between spn and Merlin is i can rewatch any ep of Merlin and i can't now rewatch any of spn eps because the last couple of seasons killed all excitement :(

I don't feel compelled to rewatch any SPN either, even eps that used to be my favourites. Maybe a couple years down the line after the bad taste has gone away? But I'm not sure. Bad taste is really bad.
