A dark styled cartoon original aired on Nickolodeon staring Zim, a loud wreckless alien on a mission to conquer/destroy earth, Dib, a human boy with the mindset to stop Zim, Gir, Zim's disfunctional SIR unit, and Gaz, Dib's dark brooding sister who only cares to be left alone.
Invader Zim is considered by many people the "Jesus Christ" of Cartoons. Created by comic book writer Jhonen Vasques, author of Johnny the Homicidal Maniac, Squee, and Filler Bunner, Invader Zim became the prophet of his dark concepts. Revolutionary in many ways, it challenged the way its viewers looked at the world around them. The show was cancelled for its unpopularity amoung younger audiences and high production costs. The show grew a major cult following after its "crucifixion".
Throughout 2006 the show had an apparent "resurrection" where episodes never before seen on tv were aired, though they were available on DVD releases before-hand.
Even though Invader Zim is gone, he lives on in our hearts.

A show first aired on Nickelodeon, which was actually much better off before they canceled it after a couple of years or so.

It's about a green alien from a planet called Irk, sent on a fraud mission to take over the planet Earth. Problem's that he's arrogant and foolish plus such little controversy stops him, so he never exactly reaches his goal.

Possibly one of the darkest (and one of my most favorite) cartoons on Nickelodeon.

Of course, it was canceled because Nick needs MOAR time for shit shows like iCarly.

Totally logical, amirite?
Nickelodeon's view:

Invader Zim = Dark
Dark = NOT PREPPY
Dark = BAD!!!

*cancels show*

Most other people's view:

Invader Zim = Dark
Dark = NOT PREPPY
Dark = Good!!

When Nickelodeon missed it's chance for a good show.
There will never be a show as good as Invader Zim.

Invader Zim defined my childhood!

A show that gets a lot more hate than it deserves. People usually hate this show because of the sterotype that it is an "emo show", but there are no emo undertones in the show at all, and even Jhonen Vasquez (the creator) has denounced this (Search INvader Zim Fact #25 on google) (No Jhonen dosent hate his fans, dont even get me started on that rumor). Invader Zim actually has a lot of talent behind it, and a very unique sense of humor. Anyway, the show is incredibly funny, crazy, cute, somewhat dark, and even has a little satire on humanity in it. All of the characters are memorable, and every episodes plot is extremely unique for a kids show.

Sadly, this amazing show only got about 40 episodes, due to nickeloden having budget cuts. It has a VERY large fanbase (as a member of it, I must say it isnt as bad as people say), and they are currently working VERY hard to get the show back on the air (and theres actually a pretty good chance it could happen). If your into cute, dark, crazy stuffs, I would definitely recomend checking it out. All of my friends love it (me and them are all guys, btw), and they are all kinds of people. I discovered this show about a year ago, and Im still laughing at ZIM and GIR's stupidity and insanity.
ZIM: GIR... what does the G stand for?
GIR: I dont know!
ZIM looks confused and gir then starts laughing and rolling on the floor
ZIM: Um... is it supposed to be stupid?
Tallest: Its not stupid, Its advanced! (snickers)

-A normal moment in Invader ZIM.

the most overrated, and stupidest show ever. everyone loves it for seemingly no reason. Believe me, I watched the show when it first aired, and I thought it was OK, but then, six years later, it seemed like every other person liked it for no reason other than the fact that it was random or the assumption that Gir was "Funny".

Overall, I believe that shows that think that being random is funny should not be allowed to air. But this is just my opinion.

"I'M GONNA SING DA DOOM SONG NAO." Isn't funny at all unless you have the intelligence of less than an eight year old. But I must admit that it was the end of good shows for Nickolodean.
Most people who love it are random, annoying 12-19 year olds who say things like: "OMG! Invader zim is da bestest show evar cuz gir likes pancakessss!!!"
