Terrible, unconvincing, so bad.
Just Jon Bernthal's performance was impressive, that he played in a few scenes.
I don't know how a pregnant woman can fight two professional assassins. How a pregnant woman can ride horse so fast and find her husband with no telecommunication tool (cellphone or walkie talkie). Or how can she shoot two professional assassins with a hunting rifle with no night vision goggle? How a fire fighter (Julie) has no walkie talkie and needs the radio in the tower to request help for any probable danger including a fire or help for that kiddo.
and many other unattractive points....
the movie just deserve IMDb 5, not more.
