Awful. Awful. It wants to be an updated “Sunset Blvd.” with a twist. It is, though, absurd, laughable and filled with plot holes the size of Ted Kennedy’s head. The only thing even remotely of merit is, surprisingly, Mick Jagger’s performance in a side role. His dialogue is appaling but, maybe ’cause I didn’t expect it, he can actually act. I rented this because Julianna Margulies was in it — and she doesn’t even wear sexy outfits.
