Say what you want, but I love that silly Team Rocket is back (I love the serious BW Rocket too, but I've missed theyr sillyness), plus they seem to actually be a threat this time. ^^ And Inkay was awesome.
Oh, and Dedenne is also awesome of course, but one of the things I liked the most was the Whole Hole scene, when Clemont mistook Pikachu for Dedenne, haha.
Well, not all attacks fits having pretty animations and whatnot. ^^ Foul Play isn't really a 'energy' attack, it's more like Tackle in a way. Plus, it looked fairly strong.
