I found it extremely irritating and annoing that these two experienced climbers acted like complete idiots. There were at least two ways they could have used their rope to get down from the tower.

It requires superhuman strength to pull up someone hanging at the end of a rope, it is almost impossible, but not in this movie.

Why did they not think about descending the tower with the rope wrapped around the circular tower itself, just like humans have been climbing trees for centuries?

Why not tie the rope at the bottom of the ladder insted of the base of the platform? The rope would have reached all the way town to the dishes.

Too many stupidities destroyed this movie for me.
