Rambo 4 trailer... Just a warning for the squeamish, People and body parts go squish (literally, you hear squishing noises) during the second half.

The first half of the trailer kinda reminds me a typical sci-fi original jungle monster movie. However, according to my husband, it appears to have more plot then the first 3 combined.
