I don't generally give poor reviews but let me say this one is horrible in every way. Horrible acting, horrible follow through on characters, horrible segues between scenes and on and on.
There is a lot of walking. They don't drive when they can, they walk. They jump off a train- to walk. They don't run after the bad man who has kidnapped the pretty girl- they walk. They are even walking when the cave is falling down on them and they may day.
The music is good and it swells when it should, indicates danger when it should, and shows a nice light happy feeling at the end. Unfortunately, dramatic, swelling, suspenseful music will not make for a suspenseful moment if the characters don't act suitably scared, brave and yet with trepidation.
This movie left a lot to be desired. Do not fall for it. The cover looks great, it sounds exciting and yet it is not.
