 * 2) He has great lines of dialogue, aside from usually being a silent boy.
 * 3) He comforts people who feel anything but happy, namely Isabella.
 * 4) He is always calm, no matter what.

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) That moment where he yelled at his own sister Candace for screwing up their attempt to bring back the superheroes' powers in "Mission Marvel" was mean-spirited and out of character, even for him.
 * 5) * The another moment where Phineas yelled at Perry, even when he reveals his true identity, is also mean-spirited too.
 * 6) 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.
