Katy Perry wasn't listed as the 'SNL' musical guest last night (that was Robyn), but, boy, she sure did sing a lot. Of the eight segments that Perry made an appearance in, she sang in six of them. I'm sorry, but that's pretty telling that the writers didn't know what else to really do with her. And to be fair to the writers: from what we saw of Perry, they probably did the best that they could. And it's always a bad sign when the host plays his or herself, which, yeah, she did that, too. I appreciate Perry willing to stretch herself as host instead of "musical guest who also appears in a sketch", but, yeesh, this was pretty bad. Not even Matt Damon and Val Kilmer could save this show. But, hey: At least Kristen Wiig had a good show. And 'Weekend Update' saved this show from being the worst of the season. Barely. On to a pretty ugly scorecard...
