More Show More Episodes Critic Reviews for Invader ZIM Season 1 All Critics (13) | Top Critics (5) | Fresh (13) | Rotten (0) The animation's angular look and the characters' big, expressive eyes give Invader ZIM a distinctive look. Jan 31, 2019 | Full Review… Lana Berkowitz Houston Chronicle Top Critic The show's sense of humor is somehow dark without being bleak; even when the show takes its cues from horror movies - it's often quite scary - it's somehow never too much. Jan 31, 2019 | Full Review… Sam Thielman Guardian Top Critic The cartoon captures a nice blend of the innocent and the satirical, and should appeal to Nick's core audience of youngsters and early teenagers. Jan 31, 2019 | Full Review… Steven Oxman Variety Top Critic The deliriously original Invader Zim rocks. Jan 31, 2019 | Full Review… Lynne Heffley Los Angeles Times Top Critic Invader Zim not only holds up incredibly well, it also feels like it was rather ahead of its time and maybe it would have lasted longer today. Jan 31, 2019 | Full Review… Sean Aitchison CBR Invader Zim is a perfect example of a cartoon that straddles the line between children's and adult entertainment. Jan 31, 2019 | Rating: 3/5 | Full Review… Andrea Graham Common Sense Media The shows weren't consistent. Some were absolutely hilarious, while others were just, eh. Real scientific description, I realize. Feb 1, 2019 | Rating: 7/10 | Full Review… IGN Staff IGN Movies Invader Zim is by and large an unapologetically goofy show, which is a big part of its appeal. Jan 31, 2019 | Full Review… Joe Matar Den of Geek The strange and fantastical spaceships and technology that creator Jhonen invented for his world, along with a hint at the show's humor and art style, all of which help demonstrate what made Invader Zim the cult cartoon hit it still is today. Feb 1, 2019 | Full Review… James Charisma Paste Magazine The spastic E.T., along with the world around him, capitalizes on cheeky, masochistic, and random humor in ways viewers of all ages can appreciate. Jan 31, 2019 | Full Review… Sean Fitz-Gerald Thrillist If you prefer your humor to be equal parts dark and random, then it's time to re-watch this short-lived Nicktoon. Jan 31, 2019 | Full Review… Kayla Cobb Decider Invader Zim is without a doubt one of the strangest and chillingly creepy television programs to debut on Nickelodeon.

What's Invader zim? Look it up Zane b Sep 23, 2019 It's one of the best shows I've ever seen! TJ D Oct 17, 2018 Though the art style is amazing, the jokes make very little sense and are only funny about 10% of the time.
