Battleground is a movie that has been done before. The only thing is that each of its elements were in different movies (for example: Predator - except that the predator in that was a science-fiction alien and in this he's real)! Basically whilst certainly not a great film of the genre, Battleground is worth the time taken to watch it. Unfortunately, the director fell into the same trap that so many others have succumbed to whereby there is a scene where the predator runs away from three heavily-armed men through the forest. All three are letting loose with machine guns (at least one with one in each hand!) and yet the only person who gets anything like a hit is the cameraman who manages at least three seconds of a clear shot of the fleeing man's back whilst the three pursuers cant even scratch him! As I say, this is nothing new, It happened in several Arnold Scwartzenegger films where several good guys (or vice versa) fire several hundred rounds at the fleeing bad guy (or vice versa) and yet the bad guy, with only a hand gun manages to take out more than one of them over his shoulder. It insults the viewers' intelligence and, in my case anyway, cost some points in my rating of the movie. Other than that though, Battleground is definitely a thriller - although, with just a couple of brief exceptions, not really a horror film - and, as I say, worth the time.
