Technically it came out very late 90's to the point of being an 00's cartoon. By that logic, Spongebob should be on the line up as well...especially because Spongebob actually predated RP by 3 months. No kidding. SBSP premiered in May of 1999 while RP was August of that year. I guess the X-Games tie in was too 90's to not put on the line up. But when you have stronger, better shows with larger fanbases like Ren and Stimpy, Hey Arnold, Doug, and Rocko, you wonder why The 90's are All That block didn't push for more classics, and not a show that basically came in through a technicality. It's still part of The Splat's line up, but thankfully, we've seen the block more varied and longer to support better classic Nick shows. I think that's what the 90's Block's weakness was. They had a 2 hour window (they repeated to fool everyone into thinking it was 2 hours), and that lead to a small rotation of a few shows. And while those were of the Hey Arnold, CatDog, and Rugrats variety (also... there should have been a pre-movie, or at least pre-second movie cutoff for the Rugrat episodes), Rocket Power got a cushy weekend spot it really didn't deserve while stuff like Rocko, Angry Beavers, and Ren and Stimpy were only temporarily on the line and barely added back in for theme weeks.Because you were not the only person who watched Nick back then . There are lots of people who like Rocket Power.
Now, I do have a small beef with The Splat. Other than the time shift programming (at least it's on longer now), they are absolutely bonkers with piling up the commercials. So much so that certain shows only get half an episode aired. Sure, they're of the 2 11 minute cartoon variety, but it's kind of a cheat. Plus, at least with this week if I see that Sour Patch Kids commercial where they yank on the kid's non-existent chest hairs ever again, I'm going to lose it. Seriously, if you haven't seen it, there's such a painful special effects fail. They get the smoothest chested guy they could, so instead of pulling on his hair, it looks like the Sour Patch Kids are painfully jabbing into his skin with a Christmas Tree Ornament hook. Very pleasant.
Zim's of the modern era where they basically (long rant short) seemed to sabotage their animated line up if it wasn't Spongebob. It got much worse when (another long rant) Nick tried to compete with Disney channel and amped up production on live action kidcoms. They're still pulling this today, and something tells me the success rate of the kidcoms is much lower than they think.Omg, Invader Zim! Can't believe I forgot about until 2007 when I re-became a HUGE fan of it again. Until 2009 until I got in to South Park.
