At least this episode had me laughing throughout. It was great to see Team Rocket's entire lineup in the episode, the new credits, and the whole thing with spoink. My two cents:
-- The scene where Team Rocket kept trying to get clamperl to open up was ROFLOL hilarious.
I liked James having Chimecho try to get it open, Jessie's head swelling in anger, and her breathing fire (Jessie breathing fire never fails to crack me up).
-- The random chibi moment with Jessie was odd, but it was funny.
-- Brock dragging Max away, thinking he was clamperl, was hilarious. I forget what other episode he did the same thing in before, though.
-- I loved spoink putting all the various pokemon on his head. The part where he put wailmer on his head had to be the funniest.
-- I wish we could have seen spoink again, it was a pretty funny two-time character.
8/10 for me, a strong season opener.
