>actually found it to be enough like the old show but with some nice revisions to the characters (Gaz actually showing she's family to Dib, Membrane showing he legit loves his son, Zim actually coming off as threatening)
I wasn't too fond of the Rocko Revival (too preachy). Samurai Jack went down in flames early enough. Korra was just more bad Avatar. I didn't care for the Hey Arnold movie since I didn't find the title character to work for me (and even in the show I found the side-characters to be better to watch). But Zim actually worked out unlike other sequels/reboots/whatever.

Knowing the ending, I'd be fine if that's the honest end of Zim (I thought it gave enough closure for the kind of series Zim is). If Vasquez wants to do more though that's alright too. I'd trust him.
