Ebert : ★★★★
Bigelow uses no phony suspense-generating mechanisms in this film. No false alarms. No gung ho. It is about personalities in terrible danger. The suspense is real, and it is earned. Hitchcock said when there’s a bomb under a table, and it explodes, that’s action. When we know the bomb is there, and the people at the table play cards, and it doesn’t explode, that’s suspense.
