Cliche, trying too hard to "make it thrilling". Doesn't make sense when the characters were hurt so badly but can still come back fighting.
This movie should be called "Breath it loud", the actors who aren't supposed to breath, breathing, panting and whining so loudly as though a blind man isn't sensitive to any possible tinny bit of noise.
Going round and round, back and forth, just to end up in the same place. This movie should have ended 1hr10 ago. 20min should have been sufficed to tell the story.
