Cilan's scream. His scream. Highlight of the episode for me right there. Also, the Litwicks were so cute...but surprisingly pretty creepy at the same time. Nice. Team Rocket looked so awful most of the episode, I was starting to feel sorry for them. ): I'm glad they didn't get blown away forcefully at the end. They should retreat via jetpack all the time now; it's less demeaning than being blasted off.
Overall, it was a good episode. Suspenseful, humorous, and creepy at the same time. I liked it. ^^
