Why It Goes Across the 2nd Dimension

 * 1) Amazing plot and engaging storyline.
 * 2) Great animation, which looks as good as the TV show.
 * 3) The characters from the TV show still have their personalities, and are thus still likable and great.
 * 4) Great humor.
 * 5) The songs are still fun to listen to.
 * 6) The idea of traveling to another dimension seems rather interesting.
 * 7) The voice acting is still great, like the show, as the voice actors from the show return to reprise their roles.
 * 8) A very shocking moment when Perry had blown his cover in front of the boys because Platyborg was about to punch them.
 * 9) It teaches kids that they always have a different side to them, and whenever they are afraid, they can always come through.
 * 10) Doofenshmirtz was an awesome and funny villain, but his 2nd Dimension counterpart is even better as he is proven to be far more intelligent than his counterpart and he actually succeeded in taking over the tri-state area in his world.
 * 11) Perry the Platyborg is an entertaining secondary villain who eventually turns good.
 * 12) The action is fun to watch, as always.
 * 13) Isabella and Phineas finally kiss for a change onscreen, which is just so heartwarming and cute. Speaking of which, Isabella is still so cute.
 * 14) The scene where Phineas gets angry at Perry for not trusting him enough to tell him he is his pet is a nice change of pace for his usually optimistic personality and quite heartwrenching.
 * 15) The ending where Phineas and Ferb lose their memories of Perry as a secret agent, and Perry learns his lesson never to reveal his agent self in front of the boys ever again, was a pretty good touch and is very emotional.
 * 16) There’s a great callback to many episodes of the first 2 seasons in the 3rd act where it shows many of Phineas and Ferb's inventions they ever built.

Bad Qualities

 * 1) The scene where Phineas yells at Perry for his long-term deception, though emotional, can be very mean-spirited, that' because he thinks Perry didn't want to trust him but he couldn't tell him because O.W.C.A. will relocate Perry. But it wasn't his fault, he was hurt and he couldn't understand why Perry didn't want to because Perry can't talk.
 * 2) While 2nd Dimension Doofenshmirtz is a very entertaining villain, his backstory and motivation are extremely weak. The reason why he turned evil in the first place is that...he lost a toy train when he was a child. Granted, that this was made for being played for laughs to poke fun at and that 1st Dimension Doofenshmirtz even says it’s lackluster, but still.
 * 3) The way Perry the Platypus defeats Perry the Platyborg is pretty silly.
