Hmmmm - I'm starting to get worried about his series. My fears from earlier a being realised. The plot isn't moving on quickly enough, there's no clear story arch, the whole thing seems far too episodic. The characters aren't developing fast enough, either. They are developing (There was a point where Nylocke acted seriously for once, we also learned a bit about the real lives of the characters, particularly Gamercrazed), but sure enough, they're starting to feel shallow. The only two characters I can say I feel are perfect are Kirbopher (probably because he's just real life Kirbopher) and Rockoon (because he's just too crazy-awesome for me to care about character depth. The Slime-guy, Demon King and the mysterious bad guy are also brilliant, real-feeling characters. I'd like to see more stuff like with Demon King, who had real life reasons and justifications for his actions. However, I understand that its a cartoon, and that it doesn't need to be too realistic. Maybe it feels uncomfortable because some characters are deeper than others.
Another smaller niggle is that, although it was overall entertaining, there were no laugh out loud moments for me (unlike in previous episodes). Maybe you're getting a little bored, running out of jokes - so spice it up a little! Make it more interesting! I know you won't want to change the story, but maybe if you make the characters more real, the jokes will come easier.
Overall, still an amazing, well done series with lots of time and effort put into it. Just don't let it get boring!
Thanks - a concerned fan
