Commonly viewed as the black sheep of Nicktoons, that got cancelled after 2 seasons, "Invader Zim" was ahead of it's time with it's blend of bizarre characters, a bizarre setting, and dark comedy. The premise is simple, an alien tries to take over the Earth, but the episodes were able to add enough to make the show more than that. So many funny moments, quotable moments, and great episodes. I would normally do a "Best and Worst Episodes" list of this show, but there are no real bad episodes here. The show had a way of hiding weaker episodes behind enough humor to make them watchable. Episodes like "Abducted", "Chickenfoot", "The Girl Who Cried Gnome", and "Mortos Der Soulstealer" are admittedly pretty weak, but they're still watchable. They don't drag on, and there are still some lines that get a laugh out of me. Maybe it's best that this show came out when it did. It introduced a young audience to a different kind of humor, had a short run, and then developed a cult following. I think if this were made today, it would just exist to make as many memes as possible. A dark comedy with strange characters, strange episodes, but still original and incredibly funny. A fantastic show, with enough doom and laughs to spare.

I might be a little bias since I am a super fan of this show, but it's just so great. The entire entire premise, the characters, and comedy mixed in with alittle action here and there. It just makes for a good series. Jhonen Vasquez has that dark side of humor that he added into this that made it super funny, and that's what I think the IZ fanbase lacks when making fanfics of this series, his random, darkish, and snarky sense of humor just makes it one-of-kind. I can't wait for the TV movie and I'm expected to be entertained just as much as I was with the original series.

I love this show, a lot. It's unlike ANYTHING I've ever seen on Nickelodeon. We've had some good shows on Nickelodeon over the years like My Life As A Teenage Robot, Avatar, Hey Arnold, etc. But I have never seen a show from Nickelodeon that has become a huge cult classic. This show is deliciously dark for a Nickelodeon show. And some of the scenes from this show still shock me to this day because they seem like things that wouldn't get past the censors. The show is also really funny. I've always liked Jhonen Vasquez's twisted sense of humour. And it works really well here. Main highlights from the show are: ZIM yelling ''Your lying!'' over and over, GIR saying things that are so random that it comes across as cute and funny, the dark settings, Bloody GIR being hidden in different frames throughout the show, there are so many highlights here I can't even say all of them, you really have to watch it yourself to understand what I'm talking about. But still, I enjoy this show. And that enjoyment is mainly made out of me laughing and being disturbed by this show. Make no mistake, it's the darkest Nickelodeon show ever created as well as the most disturbing. But there is plenty of humour in the show to balance out the darkness. Great show all round. Not the best cartoon of all time, but definitely Nickelodeon's best.

I only started watching this in mid-September 2011 and I've realized how funny this show actually is. I've downloaded all the episodes and I can't stop watching this. Richard Horvitz voices Zim so amazingly well & Rikki Simons is the perfect person to voice GIR. Even though GIR may be the funniest character on the show, my favourite character would definitely have to be Zim. He's very awesome as well and he knows that his rival, Dib, will never get to prove to anyone that Zim is actually an alien with a very cool disguise. I don't like Dib as much as what Zim does, but one day, Zim WILL destroy Dib and then he won't have to put up with Dib anymore. Doom to Dib and hooray for Zim! I haven't forgotten about GIR. He's Zim's crazy, silly, but funny robot servant, even when he's in his dog disguise and singing the Doom Song. GIR even says some of the most random, but funny things in a lot of the episodes. I know Zim can't stand GIR sometimes, but GIR can be quite helpful when he's helping Zim defeat Dib. I would keep watching 'Invader Zim' episodes every day, even when I get older and to finish off this review, episodes with only just Dib and Gaz aren't as funny as the episodes with Zim and GIR, which is true. Like the title says, 'You rock, Zim!'
