Good film until the awful ending

Rating: 3/10 (8 February 2016)

This was a good (if not too long) thriller that should have been so much better. I refer to the ending so if you don't want to know come off now.
Hugh Jackman's character is seen as a tough guy who can certainly handle himself,that is until he comes up against a little old lady in her kitchen. He then acts totally out of character and does exactly what she asks even though it is obvious that she is not going to let him live, and he won't rescue his daughter. In the kitchen he could have easily over powered her, OK she had a gun but so did he in his bag. Or when she gave him the drink to weaken him, what does he do? He drinks it rather than through it in her face.
Then the most stupid part. He gets into a car and reverses slowly as she asks him to, rather than reversing quickly to knock her over or oat least off her feet. And then he jumps down a hole so she can lock him in with the car over it.
Sorry but none of this makes sense and it spoilt an otherwise good film.
I also thought that Jake Gyllenhaal was a poor choice for his role as a cop, he was clearly unhinged and hindered the investigation, (then maybe cops are like that?). Terence Howard's character was the only one I believed out of all the parents and Paul Dano plays his part well as the mentally backward son of the nutty woman.
I also thought that the film had too much unnecessary bad language, (Then I always find that people swear and curse more in movies than I ever find in real life(, But I put up with it as the story was gripping until the end.
It is a real shame that this film ended the way it did. The silly ending with the whistle noise was so predictable as to almost turn this into a comedy.
