This movie is very unrealistic, however I like this movie because it reminds me of Call of Duty 4 Modern Warfare (not the bats the terrorists). This movie has a terrible story, Russian terrorists are using Bats as a weapon and America is sending in Spec Ops to stop them. This movie isn't completely terrible, the action scenes are moderately entertaining, I mean you won't die if you watch this movie. I've seen this movie twice and don't hate it, but am definitely not a die hard fan. This movie is on the sci-fi channel and if you've seen their movies you know what its like. The effects are just okay but the action scenes are pretty unrealistic.
Now the DVD
The DVD does not have too many extras, in fact all it has is a few deleted scenes. I don't recommend you buy the DVD without watching the movie. (It can be seen on the sci-fi channel).
