These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Xenozoic Tales
Animation Age Ghetto: Basically what killed the cartoon after a few episodes. They tried to make it a smarter, darker TMNT-killer and it was a bit too heady for a Saturday morning cartoon. Maybe if they had revived it for the Cartoon Network era it would have had more success...
That One Boss: The arcade game is ruthless but Tyrog and Slisaur are the toughest bosses in the game aside from the Final Boss himself. The former is due to you fighting him three times, each stronger than the last with little health recovery if you're lucky. The latter is being a Dual Boss if single player or three bosses in multiplayer. If you had a hard time fighting Slice by himself, good luck fighting more of them.
