No totally disagree with the critics ... this movie is showing most likely what a "normal" person/wife/mother would do if angry enough. OK so there are obvious gaps in details for the plot of the movie (how she got out of the country with only the clothes on her back) but who GAF?? I totally get the feelings of "I wanna die because my family are gone": and it makes sense her going into cage-fighting as incredulous as it may seem - we assume she was a wimp before the incident ... maybe not so! She never cared if she died as long as while she was alive she did her best to avenge her family. I think the story IS solid ... my only issue is the filmmakers tried to do a Bourne Identity finish on the movie ... nah! I would only half heartedly watch a sequel. This woman already did what she had to do ... her avenging was a vigilante with a cause: that cause was her family's death. At heart she was never supposed to be Charles Bronson or Steven Segal ....
