Here's an interesting blog article that brings up some of the issues that I had with the show.
Why did they wimpify Sarah Connor?
I want the drama to fit better into the storyline and not just be an excuse for another shoot-em-up scene between the robots. The hiding-out aspect of the story feels a little too much like the hiding-out aspect of Heroes, especially since the actor playing John Connor looks so much like Claire's boyfriend West from this season of Heroes.Summer Glau is great as a killing machine, but not so great when she's pretending to be a normal girl at first. So if it's true that future episodes will feature her character going to school with John and trying to act normal, that could be an issue. Thomas Dekker, as John Connor, has a bit of a mouth-breathing issue.
