The formulaic storyline follows a ragtag group who parachutes out of nowhere on to a jungle planet where they are hunted by Predators.
The group consists of a mercenary, mexican drug gang enforcer, deathrow inmate, Yakusa enforcer, etc... you get the idea.
Imo, this is another film where they spent "maybe" three days on script writng/ character development and maybe a couple hundred $$$ on special effects...ultimately neither provide anything new or interesting to the series.
Nowhere near the originality or hillarious deadpan interchange between characters as in the orignial. I'd wait til it comes to dvd and even then don't set your expectations too high.
