This was an OK episode. I liked how Brock fell in Love with the female teacher and grabbed her hands to flirt with her, but later got scared when she yelled at the kids. I thought It's harsh when she yelled at the children like that, she should've been more considerate with them.
It's really funny when those kids were playing Pikachu's face, but Ash pulled him away from the kids before it could zap them. That scene was my favorite scene from the whole episode, and it'll remain a memorable scene to me. I also liked the scene when Brock said "That's All Folks". That was a nice Looney Tunes reference, and I think it fits the theme of this episode.
I didn't really like the parts with Team Rocket and Mewoth in this episode. Also, it's very rude of Misty to hit Ash and Brock on the head at the beggining of the episode, she shouldn't have acted so violently.
