Ashley Padilla is the best new SNL cast member and one of the best members of the current cast overall. (I know she started last year, but I still consider that new.) Her delivery is fantastic, she has great technical acting skills (projecting her voice, annunciating clearly, and other things I'm not knowledgeable enough to pinpoint), and her characters are always funny and believable.
The show needs to let her spread her wings a bit. She can't always play the mom, although she plays that role well.
I predict she will be big.
