Loved the plot, disliked the characters

To much stupid things.

Busdriver robber: was he retarded? For exampel, they can't get into the room if they are passed out, his solution: kill them.

They can't go inside the room with a sledgehammer and as he pointed out about the noise later (dont wake the neighbours) he still banged the roof like an idiot.

When they acctually needed the girl for bargin, when the mother was outside with a gun. He didn't want his companion to give the girl her medicine (even though she stated out that she would die).

He was beating the husband for no good reason. He didn't help with the break in, he didnt helt with the safe, What exactly was his funcion in the drama except being an idiot?

The mother: was about to run out from the room when she didnt have vision on all three on them. Cameras were pretty much covering the whole house, she could have waited.

When her husbands new girlfriend answered she could have just screamed for help in panic instead of asking for someone else first (same with the 911 call).

She knew they couldnt hear her when she talked to the cops, why not just say: They have my daughter locked up, if you come in they kill her. Please act like your going away.

Why did she give away the gun to a man who cant stand, lift his arm and barely see? she could have used him as a decoy, giving him a pointless knife or something.

_____________

Mother and daughter: Why did they stop blinking with the flashlight on the neighbour? No way he was going to hear them. Why didn't they search the room when they found out something was in there? Why didnt they try to bargin or come up with any real soulution with the robbers when she knew they wanted something in the room.

Idiot robber: One of the robbers were incredible stupid, he was stupid through the whole movie though so that character was oki i guess.

I probebly missed something, acting was great though (in my opinion). Plot was cool to. It's probebly just a personal thing but i can't stand characters in some movies.
