Spoiler Alert'

I finished watching Super Robot Wars OG: The Inspector last night, and felt completely satisfied by the ending. Why?


 * 1) The protagonists rocked. The good guys faced hugely powerful foes, and proceeded to whale on them. They didn't worry about it, they didn't have long debates. I want shades of gray in real robot series; not in super robot series (at least, not in the end battle).
 * 2) The end included a denouement. Seeing the fate of each character--even if just for the next couple of months--provides an important feeling of closure. There's a reason that fairy tales end with "And they all lived happily ever after."
 * 3) The ending included a lot of fights. This is a super robot show; fights should be central. And the final episode of SRWOG:TI consisted almost entirely of wall-to-wall showdown fights.

That's how to do it.
