Hey, how about an hour-long Saturday Night Live?
That's the idea from Matthew Gilbert over at Boston.com: reduce the length of Saturday Night Live from 90 minutes to 60 minutes.
Would it help the show? We all know that the weakest part of the show seems to be that last half hour, when the lame sketches air. Regardless of what many people say about the current SNL (including me), there's still a lot of talent on the show and there's a lot of good, funny stuff that comes from it. Unfortunately, all the funny stuff doesn't come from the same episode. I'd say there's usually two really good sketches in an episode (including "Weekend Update"), a couple of "oh, this is a good idea but not for a sketch this long" segments, and several "how did this make it pass the writers room?" disasters. Maybe cutting the show down to an hour, while not perfect, would make the good parts stand out more and really get the show lean and mean again.
There are two problems, of course. Less ads, for one, but as Gilbert says, maybe a better show will get more people tuning in week after week. The other problem is the musical guest. They'd probably only have time for one song now instead of two. If the bands are OK with that, I think it's something NBC and Lorne Michaels should give some thought too (though I bet they have already at some point).
