So by this point in the series I'm burnt out, not interested in the mystery, and disengaged with the tension in the story.  The cops looking for Gwen's dad should be heartwrenching and it does go through the right motions to convey that, but I think Miracle Day is just so dragged out that I just can't really bring myself to care anymore.  The Gathering leads us into the last episode adequately, but on its own it is just a mediocre experience with little worth revisiting.
