That ending felt like a cheap cop-out... probably didn't get nearly as much popularity as they were needing from Publisher, of course, a lot of the story felt like they were just jumping and jumbling around everything. It all felt super messy and unstructured. For that... in my personal opinion... 3/10.
"ONLY THREE!?" You might ask? The artwork was nice, and some of the material IS excellent, but... the rest of it just brought everything down on it's head. And the ending was so rushed, but felt like they probably put more into it than into the rest of the entire story combined... probably because they knew they were having to axe this series...
