This is my new favourite show, it's witty, the characters are awesome, the premise is awesome, Dib is awesome, I couldn't wish for more. It has a reputation for being dark, and it is, but if we're being honest kids these days watch marvel at age four. This cartoon holds nothing to the violence there, so don't let that worry stop you from watching! (Plus, Dark Harvest isn't half as creepy as The Worst X-mas Ever or The Halloween Spectacular of Spooky Doom)
I'd recommend Invader Zim to anyone!
