Robin Williams is finally back to doing what he's always done best -- off-the-cuff riffing on whatever subject you put in front of him. He's brilliant. While America's sense of humor has changed a bit since Mrs. Doubtfire, Williams' ability to turn his incredible sense of humor into a source of drama (it's obvious that his characters' silliness is a response to his own desperation) shows that as an actor, he's gone from silly to serious and come back out the other side with a remarkable ability to showcase the two simultaneously and sensitively.
Sarah Michelle Gellar is perfectly cast in her role, as a foil for Williams. Her ability to (act like she can) see the serious and important sides of absurd and silly situations -- honed to a keen point in Buffy -- is exactly what Williams' character needs to have the truth of his tragicomic situation highlighted.
Also, this is the first show that I've ever seen where the unabashedly promiscuous person (Zach/James Wolk) is a guy -- and it's AWESOME! The way that everyone treats him (the line was something like "Zach, lose a layer. If it goes badly, two.") is perfect. ("To be safe, I'm going to need some meat. Zach! Vaya con queso, amigo!") I realize that Zach is theoretically supposed to be the main character of the show, and honestly, he's *almost* able to hold his own next to Williams and Gellar. Give him a few episodes, and he'll shine. He's pretty and obviously a great actor, and I can't wait to see him blossom.
This show isn't going to appeal to everyone -- it's paced like Scandal, has the emotional volatility of the Newsroom, and the pop culture references of Franklin & Bash. ("Lopez wants to be paid in diamonds, Aidelle is British...and Pink threatened me.") The problem is that it's billed as a zany comedy/Mad Men with Robin Williams, but the truth is that it's actually a very dramatic story hidden beneath zaniness, and a lot of people are going to have a problem with that.
