Enter would somehow make SpongeBob even more stagnant than it already is. Given the state of the show now, that's quite an accomplishment, but past experience shows that Enter cares about only one appeal when making or criticizing content: His own.
Personally, what if Enter tried to review an anime, like... just any whatsoever. For the guy that went into fucking depression over Fluttershy being a jerk, I'd love to see him tackle a show that tends to get a little more dark than that. If he tried to review something like, say, Madoka Magica, he'd probably go into a depression-induced coma after the third episode.
... Bah, who am I kidding? He'd probably pick something more mainstream like DBZ or one of the recent seasons of Pokemon and then bitch about animal abuse or how mean-spirited everyone is or some other mundane crap.
