Louis C.K.'s comedy and the new mockumentary The Comedians start Thursday on the FX cable network. Both are unusual and ambitious, says critic David Bianculli, but only one hits the ground running.

Alex Gibney intersperses recently unearthed concert footage from 1971 with vintage and newly recorded interviews to make Sinatra: All or Nothing At All. It's illuminating and by no means a puff piece.

The Late Late Show with James Corden fills the post-David Letterman time slot on CBS. TV critic David Bianculli says that based on first impressions, Corden will "settle in nicely."
