The main problem I had with this episode was the Kaia subplot. I understand the writers and directors wanting to tie up loose ends, but it felt like a waste of an episode. We're over halfway through the season and I expected more. However, I did like how Chuck was destroying the other worlds in order to "get back to basics". Also the actress who played Merle was flat. This episode wasn't bad, but it could've been much better. I hope next weeks episode makes up for it.
