The movie has quite the important issue as a topic. Child abductions are not something to take on lightly. The pain and suffering parents go through ... I do not wish that upon anyone, friend or foe. That being said, the movie unfortunately deals with some issues of its own. One of them being ... cliche traps it falls into.
The other major thing the movie has to deal with - acting. Or rather the lack thereof. No offense to all involved, but there are some odd choices to say the least. So while the drama is high or should be - you may be quite distracted by the lack of real emotion in many scenes. Of course this also has other issues (script, directing choices and so forth) ... nothing that would make me say this is really bad - but you may see it that way. Depending on how much slack you are willing to cut and give the movie for being brave telling this story ... no matter where it ends ... or how it ends. Not that you can't see it coming.
