Yeah the ending could have been better. I mean, I feel like it's meant to be a movie and not a representation of common-survival-instinct act. I understand that it must feel thrilling and action paced, but if putting myself in their shoes, I would not keep speeching to my enemy and would shoot instantly in order to survive. But no doubt I enjoyed its scenery and uncertainty. Some scenes seem forced, out of place and very unlikely. After all, it's meant to be a movie. Our mistakes keep haunting us tho.
