Phineas and Ferb orginaly aired 2007, it had 4 season. Phineas and Ferb's season 4 ended in 2015. Now 10 years later Phineas and Ferb are back! But was it worth it? Did Phineas and Ferb live up to the hype? Yes Phineas and Ferb lived up to the Hype. The orginal 4 seasons had brand new catchy songs for every singal episode, and the new episodes have just that.In the orginal seasons the two step brothers would make new wacky inventions every episode. Those two step brothers still make new wacky inventions. In the older episodes the step brothers sister Candace would try and bust her little brothers for making wacky inventions, and she still does that. The brothers pet Perry in the older episodes would fight an evil scientist Dr. Doofenshmirtz. In the new season Doof is back to his evil ways, and Perry is still taking him down. What I am trying to say is that Phineas and Ferb lived up to the hype. Co-creators of Phineas and Ferb Dan Povenmire and Jeff Swampy Marsh found away to stay true to the orginal, but make the new episodes feel like the show was a continuation, not a remake that was their goals, and they did just that.
