Overall, this was a good series, enjoyed it, but maybe since it was cancelled midway through they ended the show kinda lazy and lame. But, in the end I can see why NBC had doubts if the writers could continue the series beyond season 1, and cancelled it when they did. Maybe the writers had a plan to go on for a few years, but I couldn't see it.
The investigation and the kidnappers storyline was good. The kids scenes were the only boring parts of the show.
In the end Gibson figured out that Meg had his daughter and he wanted to kill Ian because he was a loose end that could testify that he killed Jin Lao.
