I dunno, I still have trouble calling anything a "bad episode" per say. That's not to say the show doesn't have variable quality. But there's only really one hour of the show I'd say that borders on unwatchability ("Tigh Me Up, Tigh me Down"). Unwatchability, or at least a feeling of embarassment at watching something, is my big indicator that an episode is bad.

When the show dips in the second and third seasons (and mostly the second), I think the better adjective is "disappointing".
