Early in the movie, the tail of the small plane the two main characters are in, neatly falls off and blows far away. After the plane crashes, the night comes and goes and they find themselves on a mountain. We see that the tail somehow managed to climb the mountain in a heroic effort to reunite itself with the fuselage.
With no recognition whatsoever for its impossible accomplishment of becoming animate, overcoming most of the more difficult rules of physics and humbly relapsing into an inanimate state, the movie continues on, one assumes, to a wonderfully heart warming rescue and happy ever after ending.
But if so, it did it without me. A movie that started with such exorbitant demands on my suspension of disbelief simply didn't get it.
