A Fairly Odd Movie: Grow Up, Timmy Turner is unfaithful to the Fairly Oddparents show for the most part, which is much better than this. Both the beginning and end credits say it was created by Butch Hartman, who also created the show, but I feel like I'm being lied to. Hartman broke the rules of his own creation, which doesn't make any sense. This is likely non-canon to the show.
Kids who have fairy godparents get their fairies taken away by the fairy taxi when they turn 18, according to the source material. Here, Timmy Turner is now 23, and he still has his fairies. According to this, kids don't get their fairies taken away until they receive their first kiss, no matter how old they are. Even when Timmy and Toodee kiss for the first time at the end, the former gets to keep Cosmo and Wanda for some reason. For most of the movie, Cosmo, Wanda, and Poof try to stop Timmy from "growing up" and loving Toodee. In the show, it says in Da Rules that one can't use magic to create or interfere with true love, and Cosmo and Wanda know that, but they use magic to interfere with true love here. Not only that, but sometimes the fairies don't disguise themselves when they're in public, and somebody could've seen them. According to the show, one isn't allowed to reveal the existence of their fairy godparents, or else they'd get their fairies taken away forever. Not only does Timmy still have his fairies, but he likes Toodee here and hates her in the show. He's also still in fifth grade for some reason, and Mr. Crocker is still his teacher.
I have some problems with the characters and acting here and there. For some reason, Jorgen is played by a live actor, has a realistic design, and isn't in CGI like Cosmo, Wanda, and Poof, despite also being a fairy. In one of Timmy's fantasy sequences, Toodee appears in her kid form and attire and is played by the same actress who plays her adult counterpart, Daniella Monet. Why couldn't a kid actress play kid Toodee? Human Cosmo (Jason Alexander) and Human Wanda's (Cheryl Hines) voices barely sound like their fairy forms' voices. Unfortunately, some of the characters from the show like Trixie, Sanjay, Elmer, the Pixies, and many others don't appear at all, and it hasn't been explained what happened to them.
The Fairly Oddparents is one cartoon that doesn't work well in live action. I wish an animated theatrical FOP movie was released instead. FOP is one of the only long running Nicktoons that doesn't have an animated movie adaptation, much to my surprise. This movie is surprisingly faithful to the source material in some ways (e.g., most of the characters are still their same old likable selves and haven't been flanderized, Daran Norris, Susanne Blakeslee, and Tara Strong reprised their roles as the voices of Cosmo, Wanda, and Poof, the sets look very similar to the show's locations, etc.) That's why I give it a 3/10. It's far from being one of the worst live action adaptations of a cartoon, but also far from being one of the best. Don't watch A Fairly Odd Movie: Grow Up, Timmy Turner. Watch FOP instead.
