BEST: the Vincent Price skit, a taste of classic SNL skits featuring a parade of dead-on celeb impersonations (see Gumby's Xmas Special). Shame on the reviewer who called Richard Burton and Carol Channing "obscure"--doesn't matter that they're from the past. That's part of satire.
WORST: Opening Republican-bash skit. Seemed more like a second rehearsal. Could not understand why they needed Ackroyd for this.
Jonas Bros. were weak performers, and Joe J proved a distinct inability to read a single line; Kevin sounded OK. I personally enjoyed that the show ran very short -- got to hear a lot more of the great SNL band's closing song than usual.
