I picked this up from the bargain bin at a local discount store. I wasn't expecting much, but boy... was I pleasantly surprised.
Dolph Lundgren, Vinnie Jones and Randy Couture all play important, but primarily supporting roles. It's the duo of Gianni Capaldi and Daniel Bonjour in their roles as up-and-coming drug traffickers who are the major focus of the plot, and the two do a more than respectable job.
They are not good guys, although Frank (played by Bonjour) seems to want to become one one day.
Much of the film is narrated by Bonjour, in a fashion similar to what Ray Liotta did in Goodfellas. You really didn't like the character of Henry Hill, and you probably won't like Frank very much, either. But in both films, the narration tends to help the audience understand why these guys are doing really bad things.
There is quite a bit of violence, foul language and nudity in Ambuhsed (aka Hard Rush). Which is pretty much what you'd be looking for in a modern action flick.
The acting is decent, the script is good, the plot is good, the score is great. The pace slows down in a few places, but they don't break anything. Don't pass this one up the next time you're rummaging through the bargain bin.
