I agree that %1,000,000 smash was a poor move name. I seriously doubt that that signified anything more than his resolve. After all, All Might isn't actually throwing around American states with each dramatic punch.

It wasn't satisfying; I get that, because most other fights in MHA so far have had more thought put into them. For a one episode fight, I'll take it and assume this won't be the norm because it hasn't been the norm. A sub-par encounter: MHA is in good company. Naruto had years of filler. One Piece has less material to work with each episode than a single manga chapter. Bleach was Bleach. Hunter even had some boring episodes and overwrought concepts. I'm not worried about MHA in the least. Any disappointment is a direct result of expectations which have been risen by a great series!

That said, if this is enough to 'break' the show for you, there's not much that can help that. There's plenty of great animu out there to try.
