"Do you trust me now?" Jake Carter (Mizanin) is a marine who is charged with protecting Olilvia Tanis (Roxburgh), a high profile whistle blower who has numerous death threats against her. When someone in Jake's organization is revealed to be a traitor he has to not only fight off the traitor but also keep Olivia safe so she can testify. This is a movie that is pretty much what you expect. An hour and a half of stuff blowing up and violence with a little plot. The main problem with these movies is that there is really no suspense. When you get to the fourth movie in a series you pretty much can predict how it will go from the beginning. This is no exception. On the other hand though, I have seen much worse direct to DVD sequels and this one was at least entertaining enough to keep me awake. Overall, another unnecessary sequel, but one that is at least watchable. I have seen, and expected, much worse. I give this a B-.
