Campy TV is good. You know this if you've ever watched the '60s Batman, Xena or a Ryan Murphy show. There's no need to label it a "guilty pleasure". Really good camp TV balances the goofy side of camp with something that is often thrilling and sometimes even emotionally affecting. It can walk that fine line with precision that should make the best writers and filmmakers envious. And even when it missteps, as The CW's Supergirl did a few times this week, it can be one of the best ways you can spend an hour of your time.
