I personally thought the scene at the end was cool with Ash, particularly how the Pokemon pitched in and blocked Team Rocket's attacks so Ash could make it through.
But you know, different strokes. I'll agree with the Team Rocket scene (although Jessie claiming she should be congratulated for saying "Go!" made me laugh), but it isn't actually new. In fact I recall them arguing leading to a blast-off a few times, notable like in DP 1 or 2 it happened. Pretty much the same way with Wobbufet and everything.
I actually found the episode fairly enjoyable. I'd say the weakest XY episode is probably the Furfrou episode for me, apart from the Wobbuffet dress-up scene. One thing I reallly enjoyed about this episode is how it looked "unique" with the bamboo shoots and everything as opposed to simply a generic forest.
