I just got back from a screening of Chicago and loved it. Everyone does a great job with their singing and dancing, was impressed with John C. Reilly. There was no weak musical number in the film. The opening is really good but then it keeps building the energy back until the final number. The songs are all performed on staged sets. Almost all happen concurrently with the action and the editing between the two, where the character will sing and speak the same sentence, is impressive. This might be my favorite film of the year. I havn't left the theater so pumped all year. Hopefully LotR:TTT will have the same effect.
