Loved this episode, even though the idea of Tentacruels smashing up buildings does seem a bit drastic. The old lady was also quite extreme and just scary in general. The part where the Meowth was being controlled actually was a bit creeperish. I didn't really like that part!
Misty catching Horsea was great. ;3 Much better than any of Ash's captures. I also like how Misty was able to connect with the Tentacruel and Tentacool. She was one brave Pokémon girl!
