This cast is funny.
Kate McKinnon (I didn't watch whatever the OP is bellyaching about) is easily one of the funniest women around.
That being said, my honest critique is this about the show:
I think their skits are too long and the show should be a lot more nimble. A third musical number would help too.
In the days I watched, I don't ever remember it being political. I guess the Commie Party didn't feel threatened then. Now every post about SNL is political. EVERYTHING the left does is political.
Sorry, but it is not funny television. People watch stuff to escape the insanity of this world if only for a short time, not be lectured to by the "entertainers."

SHUT UP AND SING
