I don't watch it very much but if they part ways with Belushi or Steve Martin, I refuse to watch anymore.
To add to your intentional joke, Steve Martin was never at any point an SNL cast member.
I'm rooting for them. I'm a fan of the franchise in general. To fully appreciate the show, you have to realize that they're putting together that full scale of a production in one week, warts and all. The very nature of that will result in about 10% of the skits being duds and about 10% knocking it out of the park with about 80% sort of in that middle territory. That's the nature of the show, and without nostalgia clouding your revisionist history, that's the way it's always been.
I don't think we saw the full potential of this group after one episode, like Godfather said. The season always starts out a little shaky. Particularly, featured players rarely get to do anything besides be guy #2 in the restaurant scenes.
Damon Wayans famously got fired for getting tired of that and played a boring cop part as flamboyantly gay to make it more interesting.
That being said, I saw promise. I would consider the Girls parody part of that 10% out of the park. Of course, if you don't watch the show it will fall flat, but if you do, you'll note that this is pretty spot on.
All that to say, one of the new featured players carried that sketch as Lena Dunham in a rare feat for a featured player in their first show ever.
For an analogy, I look at this season's SNL the same way I look at this season's Auburn football. It's a rebuilding year, so expectations must be tempered. But I see lots of promise.
