It was a fine ending. Nothing really special, but it worked. It also felt like a big throwback to the ealier chapters, with the ecchi and all, so there was some nostalgia in reading it. Overall, I'm happy with the manga; Soul Eater is without a doubt one of the better Battle Shounens out there, and I'm glad I picked it up.
Now then, BONES, get to work!
PS. If you want to know why the final count is at 117 chapters: http://myanimelist.net/manga/908/Soul_Eater/moreinfo
