Red Siren
I was really surprised by how much I dug this movie. I passed it up so many times at the rental store, for no real reason. "Red Siren" reminded me a lot of "Bourne Identity" and "The Professional." In fact, I wondered since it was French, if Luc Besson had anything to do with it. Anyway, I really recommend it for those who don't have a weak threshold for violence, and are willing to sit for two hours.
I think it's important to note that if you get English audio/subtitles off like mine was, that some of the dialogue sounds really forced and unnatural. But I didn't think anyone did a bad acting job in it.
