The Lookout (Blu-ray)

The Audio: Rating the Sound

While most high-def releases usually include at least two audio tracks, 'The Lookout' on Blu-ray features only one -- but at least it's a good one.
Though it doesn't have a lot in the soundscape to work with, the uncompressed PCM 5.1 surround track (48 kHz/24-bit/6.9 Mbps) on this disc still manages to create an intricate world with ambiance and environmental acoustics. Listen to the dialogue in a scene in the bank and then skip to one in a smaller apartment -- notice the difference? The sound designers have clearly worked hard to make each setting unique and realistic. Effects don't sound canned, dialogue is both lush and well prioritized, and there is a fullness to the soundfield that takes advantage of the rear speakers for subtle enhancements.
That being said, aside from the opening scene and the more action-oriented elements of the final act, the remainder of the film is a quiet experience that relies on viewer immersion rather than surround wizardry. As such, the majority of the track pulls forward and inhabits the front three speakers. The results aren't terribly involving, but still this track handles what it's given with a technical proficiency that sets it apart from other quieter mixes released in high-def.

is this for sure? only LPCM 5.1? what about those guys with just optical? is it 2 channel for them?
