I have a total crush on Abby Elliot. Hot funny girls are where its at. Her Drew Barrymore, Dunst, Cusack and Jolie (found elsewhere on YouTube) are dead on. Her non-impersonation stuff isn't as funny, but that more has to do with the writing.
Michaela Watkins' Arianna Huffington is hilarious. Hopefully they'll do the show some good. Wiig and Pohler are great but they havent been enough to bring SNL back to the good old day of Cheri, Will, Molly and Ana. They need better writers.
