The writing is atrocious. The only thing keeping it afloat these days is the political satire, but even that has been mediocre. The '89-'92 crew and the '96-'00 crew would have knocked that **** (Palin, Obama, Bush, Chaney, Pelosi, etc.) out of the park. You know it's bad when the audience doesn't laugh.
These days, unless they have a funny guest it's not worth watching. MadTV level. It's a shame really.
Keep Wiig, Samberg, Heder and Forte...dump everyone else...and get some new freaking writers.
