In the late 2000s and early 2010s, Phineas and Ferb was the most popular animated show on television second to Family Guy and routinely rivaled SpongeBob in the ratings. People considered it to be a ray of hope for animation, because most of what was on at the time were either shows that had overstayed their welcome or just appealed to kids, and for it's time, and before large fanbases were a thing, had a considerably wide fanbase. But by 2013 and 2014, around the time Gravity Falls and other shows came around, the show had garnered huge backlash and many people were complaining about how repetitive and bland it was, and that it kept explaining the jokes, using fourth wall humor too much, and Disney was overexposing it. Many of the people who did like it abandoned ship and refused to admit they ever liked it. It was very rare to visit a site without seeing someone bash it. When the crossovers were announced, people were ready to jump on them and pounce on them, which was enough for Dan and Swampy Marsh to put a disclaimer on the Star Wars special explaining that it wasn't canon. It was one of the most hated cartoons of all time, with only Johnny Test getting more ire. No cartoon I can think of has had a backlash as bad as PAF, other than The Fairly Odd Parents. Family Guy had also gotten similar backlash around the same time for the same reasons as Phineas and Ferb, but not quite as bad. By the time it had ended, most people were glad to see it gone and it was considered laughable if you still enjoyed PAF or Family Guy. But a little while after it ended, it seems the popular consencus has turned and the general reaction towards the show has turned more positive. When people talk about the show, it's always in good spirits and mostly talk about how intelligent it was and there have even been memes as of late expressing that people miss the show. Even Mr Enter gave the show a positive review. When the Milo Murphy crossover was announced, the consencus has been met with more excitement than hatred compared to the other two crossovers, and people were hyped for the 10th anniversary. It's not to the extent of Hannah Montana and High School Musical, but it looks like Phineas and Ferb is having a slow, but sure nostalgic revival.
