Enjoyable if you just want a “Die Hard” meets “Home Alone 2” action movie, but not very realistic. What kind of fire department goes away without at least having a quick look around? And even if the heroine was trained enough in martial arts to take out 4 or 5 thugs single-handed (spoiler alert), how would she go free after beating up 4 or 5 cops and then chasing the bad guy and killing him instead of letting the law go after him? Even Rambo went to jail for killing less people. A few script changes could have made it much more believable. All said, if you don’t care about details, enjoy a “good girl beats bad guys”movie.
