I saw the movie today, and it will take some time to recover. It's about 90% action, and it's not mere Hollywood special effects. These guys are the real deal, firing real bullets, portraying themselves in situations that SEALs must handle on a routine basis. The legendary rigors of their training requirements make more sense to me now. In the field, they need every bit of it.
The SEALs in Act of Valor won't win any Oscars, but they did an okay job of acting. It would never work the other way around. No actor could even begin to do what the US Navy SEALs do. Thanks to the SEALs and all our military heroes for their service. The world would be a much worse place without them.
