Well, it's a bit of Die Hard (set in a plane) with a few cups of Panic Room sprinkled in for good measure. Basically, nothing new, but still an okay flick.
I chuckled aloud at a scene wherein the bad guy gets a fire extinguisher to the head... if that tells you anything. :)
Always fun to see the bad guys goin' down.
Yippee kai yo kai yeh, MFer.
