Was anyone else yelling at the screen during this film?

The movie was alright, but I wonder if anyone else found a lot of pieces during the story frustrating to watch.

Mari's dad leaving the wife and half dead daughter alone in the house after just realizing the killers are in the guesthouse.

Mari's dad going after Krug and the others (who knowingly have a gun) with a fireplace poker.

After Krug jumps out the window heading to the house where his wife and duaghter are, he stays behind to fight Sadie until his wife shoots her..After that, only killer left is Krug and he doesn't even take the gun from the wife to go find him. He goes there with that fireplace poker again.

Seems the wife proved to be doing all the work. She killed Sadie, got the half dead daughter to the boat, had come come back in to rescue her husband from getting his ass kicked as well as Justin she saves the day lnocking Krug out with the fire extinguisher.

For some folk to love having an extra home in the middle of nowhere it seems, they sure as hell had no kind of security system or weapons to protect himself.

It was kind of weak the way dad kills Krug with a surgery technique to paralyze him (just because there was no rope) he had already clearly left and came back. He couldn't bring rope with him? Then a head in the microwave? Wtf? They should have just let Mari or the mom finish him off.
