Villain Hacker got off too easy in the end. (SPOILER)
Throughout the Movie the main Villain Hacker strutted his vile stuff by slapping around a small boy, molesting a young woman and threatening everyone with his gun, when he wasn't knuckleing under like the yellow coward he was to the main hero.
So in the end when he's crushed in the cave-in, I thought; "TOO EASY on him!"
A more fitting end would have been to be chewed up by the T-Rex.
