I just keep thinking of Billy West when it comes to the later versions of Doug & Ren and Stimpy. They seem to bomb to people when he didn't continue to voice over those shows. Especially Ren and Stimpy.
Billy West
refused to come back for Adult Cartoon Party. I'm sure John K had problems with that as well. After all, Billy continued to work on the show when John was kicked out, even doing Ren's voice from that point on. But that's not what made ACP a mess. It was that John had too much creative freedom, and everything was out in the open, opposed to stealthily and cleverly subtle. Especially Ren and Stimpy's...eh... relationship. But then again, I'm sure if ACD kept going, he would have got the formula right. But Ren was just DETESTABLE in those cartoons. Especially the one where Stimpy is Pregnant (SPOILER:
with a poop).
But still better than half the Games episodes.
Rugrats is the kind of jumping the shark that really broke my heart because it had started out as such a witty, clever show. The networks just run these wonderful shows into the ground until there's nothing left. It's really awful from an artistic point of view.
Rugrats was too popular for its own good. Would you believe that in the original line up of Rugrats, Ren and Stimpy, and Doug, Doug was the one Nick pegged to be the popular one? But Rugrats completely outshined all of them, it just took a little longer than expected. And because of that, the show ran on
far longer than the other shows on Nick. They were all over the merchandise and at the over-saturation point. They had marathons every day of Rugrats. it was like the Rugrats channel at one point.
But that happens with a LOT of shows. They go on longer than they should, get too popular, change the demographic, the writing gets lazy and uninspired... I can name so many shows that did that, but Rugrats is a prime example. Family Guy is the best example.
Rugrats had some very witty stuff stealthily hidden. Like Dr. Lipschitz... a real name, but the immaturity of the writers just couldn't resist. Actually, I'm not going to bother to list them all, since
TV Tropes listed most of them.
A LOT of anatomy jokes....
