Please do not ask questions for spoiling future events in the anime thread - do so in the light novel thread. It is tantamount to setting yourself and potentially someone else for an infraction and even temp bans.
That being said, I also thought it was a pretty good ending overall. Am looking forward to season two.
One thing I chuckled about were the rather anticlimactic battles. Akari walks into the control room. Thud. Over in two seconds.
