Potential to be great but never getting there.
The protagonist of the movie while skilled in self-defence and firearms is also extremely dumb tactically. The character made too many mistakes for someone who's supposed to have been prepared and trained all her life to keep safe and stay alive. Maybe the father should have put in the hours to do some intellectual training, to go with her physical training.
She kept making obvious mistakes, after mistakes, after mistakes as the movie went on. This made it soooo frustrating to watch. In the end, I started hating the character.
Her dad on the other hand is one cool S. O. B.
SUMMARY: The movie was a tad predictable, and bringing nothing new to the genre, but had moments of goodness (not brilliance).
VERDICT: Its watchable (albeit frustratingly so) on a dull boring day.
