Overall I thought this was a pretty good episode, but the show still has a lot of the same problems it always has. The only thing that confused me was the guy who was teleporting all over the place. I understand why he was, but could he control it? For most of the episode, I thought he was being pulled between worlds with no control of when he came or went. But then at the end he does a little Nightcrawler move to save Love Interest. Guess that just seemed a little inconsistent to me.
But yeah, I still think the show is good enough for me to keep watching. I just wish it were better. However someone in this thread said they enjoyed Under The Dome more than this. And that's just...wrong. There was not a single thing Under The Dome did well.
