I'd like to start off by saying I began watching this movie with a little suspicion, because I checked the ratings here and they weren't really high.
Well, my suspicion wasn't necessary. This movie isn't all about action, explosions and that sort of things. What is does have is a heart, it shows the bond between people and it explains why that bond takes place. Just not in a corny way, this is more of a mix between real-life personalities, suspension, and a big plot-twist at the end kind of like Hitchcock did back in the days. Just not that elaborate. Some comments on this movie say that it lacks originality, but what movie doesn't do that these days ? Almost everything has already been done over and over again.
As concerns the quality of acting, it's just good. Nothing more but certainly nothing less. It's nice to see Anne Hathaway play a different sort of role, besides comedy. Her co-star Patrick Wilson also performs on a high wire. Andre Braugher and David Morse are good at supporting roles and thats is simply what they did in this one. You can't say that the acting wasn't good, therefore I feel sorry that it hasn't been properly promoted because it would have had some potential to getting to be a popular movie.
Conclusion: Like I said in the beginning, it's good, just not a masterpiece. I suggest you watch it and go with the flow, you won't regret it.
