Metalocalypse:The army of the doomstar.
I watched a ton of metalocalypse when I was younger, and was really annoyed when it got canceled on a cliff hanger. Cut to just a while ago, they finally made an end movie, which I watched as soon as it was available, yohohoho. I went ahead and bought the Blu-ray, just because I am so glad that they could get it financed and wanted to make sure that stuff like that would continue to be encouraged. I’m not gonna say it is the most intellectually stimulating plot, but it has played a part in shaping my darker humor.
