Vindicated by History/Western Animation


 * Tiny Toon Adventures was overlooked in favor of other WB cartoons such as Animaniacs, Pinky and The Brain, and Freakazoid! back in its time, but nowadays, it has become extremely popular, being considered by many fans to be the true successor to Looney Tunes.
 * Batman Beyond has always been given good reviews, but never the amount of acclaim that Batman: The Animated Series has. However, as it went, fans began to love it more, and more, as it's now considered one of the best in the DCAU.
 * Transformers Beast Machines was not well received for a wide variety of reasons. Nowadays, fans that have since matured are more positive about their opinions, and others regard it more favorably than the Unicron Trilogy.
 * Invader Zim lasted 1 1/2 seasons on Nickelodeon, unable to maintain high ratings. In the following years it has become a Nicktoon favorite, ranking alongside SpongeBob SquarePants, The Fairly OddParents, Danny Phantom, Ren and Stimpy, Rocko's Modern Life and Avatar: The Last Airbender (and its spin off The Legend of Korra) as the most popular.
 * Thomas the Tank Engine:
 * You won't find as many fans that hate Season 8 as back in the day, especially in comparison to Seasons 9-16, though it's often still considered to not be as good as the first seven seasons.
 * SpongeBob SquarePants:
 * While Seasons 4 and 5 received less positive reception back in the day, many fans have warmed up to these seasons over time, especially in comparison to Seasons 6-8. Though reception for Season 5 is still divisive among some fans.
