8. Transformers: Revenge of the Fallen (DTS-HD Master Audio 5.1)
The Transformers films aren't exactly everyone's cup of tea, but they certainly do sound amazing on Blu-ray. The cacophony of giant robots bashing each other apart is truly an assault for the senses (and your speakers!). The action sequences are expansive and intense, yet it is still possible to discern individual helicopters and firearms among the wall of noise. It might not be the best film on this list, but it's certainly one of the best sounding.
