Here's a question they missed that bugged me during the movie: why was Gwen taking a taxi to the airport. Really, who does that? You take the subway to the junction station and take a different train out to the terminal. Taking a taxi--especially when traffic is a big problem--is much more expensive and much less efficient. It is also a lot easier to catch a subway on short notice than to have a cab drive to your house to pick you up. Just doesn't make sense.
I know, they needed it to be a cab so that she could see the bridge. But that's a sloppy writing flaw. Or someone who doesn't know Jack about NYC. (I've only visited a few times, but I do know how to get to the airport!)
