Not worth seeing just for the 3D, though 3D helps.
Aspects of this film were downright offensive, such as the slaughter of U.S. soldiers (the bad guys) over which none of the insurgents seems to feel the slightest moral or emotional conflict, though they have moral conniptions every time they have to kill a wild animal.
There are some ham-handed references to the Bush administration (or something): Two giant trees are toppled by the U.S. soldiers and it looks uncannily like the Twin Towers collapsing; Phrases like "shock and awe" "hearts and minds” are sprinkled throughout.
The bottom line, though, is that the film and its morals are so half-baked and incoherent, that it never got sharp enough to get under my skin.
