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: Mighty Mouse
Adaptation Displacement: Because of the massive importance of Bakshi version, no-one cares about the 1970's Filmation revival anymore.
Flat Character: Mighty Mouse literally has no personality in the original cartoons. NONE. In fact, the only time he appears is more than midway through each cartoon, acting on a established threat. Ralph Bakshi deliberately inverted this in the newer show to give the mouse some character to work with.
Genre Turning Point: John Kricfalusi explained the series' massive influence on and importance to all American animation that would come after it to the AV Clubin 2001:
It was the first series that was completely created by cartoonists: It was written by cartoonists, all the creative decisions were made by cartoonists, and we created all the characters. It was totally different from anything anybody had done. We broke every rule you could think of, everything they told you that you couldn't do.[...]A whole bunch of things we did once or twice on Mighty Mouse became whole trends in other people's cartoons. Everybody copied it instantly.
The Scrappy: Parodied by Mighty Mouse's young ward, Scrappy the mouse
Seinfeld Is Unfunny: The New Adventures suffers from this badly nowadays, especially compared to its successor The Ren & Stimpy Show. It was a revolutionary show and concept for its day, and essentially served as a training ground for future animation pros today, and for bringing back cartoon animation in the vein of classic cartoons to the mainstream in TV. Unfortunately, the actual production quality of the show has aged horribly, not helped that the show had many production woes, animation and art mistakes and sloppy execution (as attested by former staff, includingJohn Kricfalusi) and many of the jokes and satire will seem either tame or fly right over the heads of today's viewers.
