Twist-wise this is a heckuvagreat movie. It's a steaming, down and dirty whodunnit-to-who under the guise of an army training exercise gone wrong. A Special Force team goes into the jungles of Panama, under the supervision of Samuel L. Jackson (West,) but they don't all come out. The onus of finding out what happened falls on Connie Nielsen (Osborne), but then Tim Daly (Styles) brings in John Travolta (Hardy) to take over the investigation.
It's not Travolta's best role, but he does a passable Hardy, the great inquisitor. Connie Nielsen steals most of the movie, even though her accent grates on the nerves sometimes, but otherwise she's got what it takes. Timothy Daly is good for most of the movie (until the end), and there just isn't enough Samuel L. Jackson to go around.
Poor Giovanni Ribisi - he must be really tired of being type-cast by now. He plays the same role, once again, for the umpteenth time.
My problem with the movie is that a lot of the scenes are shot out of focus and in the dark - so it's hard to figure out who's doing what to whom most of the time. (My copy didn't have sub-titles, and the close-captioning was pathetic, so that didn't help much)
Any attempt to summarize the plot would contain spoilers, so I won't. Spending a few hours on this 3.5 star movie, wouldn't be time wasted.
