Zim dreams of greatness. Unfortunately, though, he's hopelessly inept as a space invader. Desperate to be rid of the annoying Zim, his planet's leaders send him on a mission to infiltrate Earth, providing him with leftover, cobbled-together equipment. To their consternation, Zim succeeds in setting up a base on Earth and infiltrating human culture, posing as a human child as he plots the planet's downfall. Only Zim's archnemesis, Dib, recognizes that Zim is an alien, and of course, nobody believes Dib's claims.

Lana Berkowitz Houston Chronicle The animation's angular look and the characters' big, expressive eyes give Invader ZIM a distinctive look. Feb 1, 2019 Full Review Lynne Heffley Los Angeles Times The deliriously original Invader Zim rocks. Jan 31, 2019 Full Review Sam Thielman Guardian 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 IGN Staff IGN Movies The shows weren't consistent. Some were absolutely hilarious, while others were just, eh. Real scientific description, I realize. Rated: 7/10 Feb 1, 2019 Full Review James Charisma Paste Magazine 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 Kayla Cobb Decider 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 Read all reviews

Gage L Best nicktoons show in the past 20+ years next to SpongeBob. Rated 5 out of 5 stars 04/12/25 Full Review jowell i love this cartoon this and hey arnold are my favorite nicktoons of all time Rated 5 out of 5 stars 01/01/24 Full Review Jorge O A really fun series. Season 1 has much to enjoy about it. It sets the tone in every episode that this show is different than anything else we're use to. Its darker, but still full of characters that will lighten your day. The quotes stick with you and thats great. The episode plots are also creative and engaging. My biggest knock which keeps it from being higher ranked, is the amount of screaming that is used. It can be quite annoying to listen to and may keep some people from enjoying the show all together. Not enough to ruin it though as I enjoy the overall voice acting as one of the best in animation. Rated 4 out of 5 stars 05/06/23 Full Review Jake D The show itself has more balls than any other kid show. These assholes from Nick cancel this show for two seasons for no reason just so they can shove more pander kid crap content into their faces like these terrible Dan Schneider shows except Drake and Josh or try to force you to go outside and play with the Worldwide Day of Play shit just so you have no choice to change the channel until this dumb event is over. The movie is great too! Rated 5 out of 5 stars 03/01/23 Full Review Audience Member Here we go, a series better than classic SpongeBob! I love this show and it's hilariously dark! This show deserves it's 100% rotten tomato score! Rated 5 out of 5 stars 01/09/23 Full Review Audience Member A show that captures good yet creepy design and characters that are so fresh yet simple you'll wonder why the show didn't carry on longer Rated 5 out of 5 stars 01/09/23 Full Review Read all reviews
