Overall

 * 1) Questionable character design choices. Even the show they originate from what makes fun of them for it.

Phineas

 * 1) Sometimes oblivious to emotions, such as Isabella's giant crush on him.
 * 2) Sometimes too optimistic in dangerous situations, such as Candace's constant and obvious methods of busting him.
 * 3) He may yell in a situation where he needs to show more compassion. For example, at first it seems like he did not want to understand why Perry kept the agency a secret from him.
 * 4) Despite what Overall WTAGDIA#1 saids and being a nice change of pace, He has been harsh on Perry and Candace which was very out of character, even for him.
 * 5) When he found out Perry was a secret agent who fight Dr. Doofenshmirtz, not only did he got furious for not revealing his identity in front of them, but also furious at him for not trying to warn them about Doofenshmirtz's true colours in "Phineas and Ferb The Movie: Across the 2nd Dimension".
 * 6) When Candace accidently switch the Marvel superheroes powers, he refused to let her help fix the machinery. Then, when she accidently turned Baljeet into a Hulk monster, He had the gall to revoked her S.H.E.D. card and kick her out. When Candace tried to apologize, he didn't even listen one bit from her in "Phineas and Ferb: Mission Marvel".
 * 7) He can easily irritated at times.

Ferb

 * 1) In the Phineas and Ferb: Star Wars crossover special, Darth Ferb's plan is to turn his brother to the dark side was a bit overdone in the Star Wars universe, like Vader with Luke, or Kylo Ren with Rey.
