Well put together and all that but really bored me...
Act of Valor tries to sell itself on that it's using real Navy SEALs, their families, tactics and that, which makes the film "authentic". But really, it just makes the film poorly acted and really dull (and probably low budget too).
Add some really tiresome writing and you've got something that doesn't really resemble an actual film but a video shown to potential recruits.
Pure American pish.
