Watching Parks and Rec last night showed what The Office could be. Paul Rudd should have taken Michael's job. He is tremendous as Bobby Newport on Parks and Rec, playing a character sort of like his role in My Idiot Brother. He could've been a trust fund baby, who is given the job due to him being the son of a Sabre board member. He could've made Michael Scott look like a genius. This type of character could have really breathed some life into the office.
Alternatively, they should've gone with Jason Bateman as a completely dry, serious, business minded character who is surrounded by the insanity that is Dunder-Mifflin Scranton.
At any rate, Andy as the main character really isn't working. It may be because they are plugging him into left over Michael plots (and when they don't do that, they plug he and Erin into left over Jim and Pam plots) but whatever the reason, it just isn't working.
