Exterritorial might not hold up to a prolonged logic check, but its action scenes more than make up for any questionable plot holes.

Ultimately, Exterritorial is the Taco Bell of action thrillers: barely satisfying, but cheap, accessible, and almost tasty.

This is a fairly entertaining action movie with mystery and suspense, but it's also a bit uneven in a number of ways.

Even with a few faults, Exterritorial scratches that mid-budget action itch that is finally starting to come into focus in the action landscape again.
