From the Post's Desson Thomson:
Staunton's brilliant comedic performance -- a frosty mixture of arch sanctimoniousness and Maggie Thatcher steel -- brings to life one of Rowling's greater creations. And the actress had this reviewer remembering Umbrages from his own boarding school days. (Ms. B, the mathematics teacher, who handed out detentions with that soft, silky voice -- a sort of velvet gloved executioner! And Ms. M., the French teacher, who liked to display her leathery hand to classes as a permanent warning to pay attention!)
Staunton is just one in a collective embarrassment of riches among the predominantly British cast -- a who's who of stage and screen that also includes a silkily funereal Alan Rickman, as Severus Snape, who makes contempt seem like a fashion statement, a wonderfully sensitive Gary Oldman, as Harry's protective godfather, Sirius Black; and an effectively eccentric Emma Thompson as Sybil Trelawney, the school's resident goofball teacher.
Emma Thompson and Alan Rickman have stolen the show(s) by a mile so far, so this should be very entertaining indeed.

And, as if that weren't enough, go ahead and pre-order the final book, and see if Harry makes it through or not. Go on, you know you want to.
