- Big-Lipped Alligator Moment:
- The Quailman fantasy, as in the case of the main series.
- Mr. Bluff has a ship's wheel in his office and when one of his mooks uses it they find it controls the angle of the floor... for some reason.
- The freaking shrink ray! The nerds built a WORKING SHRINK RAY, it shows up for one scene, and it's never mentioned again!
- Broken Base: While some fans agree this movie isn't that great in comparison with both Nick and ABC/Disney series, others say this movie is pure garbage and killed the franchise, especially the Nick Doug fans (though it turns out the movie isn't what did the franchise in). However there's also a small amount of fans who did enjoy the movie, but seeing it more as "flawed, but okay".
- Cliché Storm: A mild example. Whether this was intentional or not remains unknown.
- Heartwarming Moments: Whatever the film's other flaws, Doug and Patti's dance together is seen by many as a nice note for the series to go out on.
- Hilarious in Hindsight: The title itself is this due to the film's lackluster reception leading Disney to abandon any ideas for more movies based around Doug.
- The poor performance at the box office was often blamed for why the movie never got a sequel and for "killing" the franchise. While the movie had a fairly low gross, it did make back its budget. The real reason why the movie never got a sequel was due to Doug ending production shortly after the movie, as per the 65-episode limit put on Disney's animated shows at the time. As for the movie being accused for ending the franchise, Jumbo Pictures had already cut their ties with Disney after PB&J Otter ended. Doug merchandise actually continued being produced even after the show ended, up until 2001 when ABC removed the show from the schedule. Doug Live!'s closure the same year was the true end of the franchise as nothing new came from it since.
- The movie is also incorrectly assumed to be the Grand Finale of the show, leaving Doug and Patti's romantic arc unresolved. The show went on for fourteen more episodes after the movie and Doug and Patti became an official couple at the very end of the last episode.
- Never Live It Down: A mild example, but it was widely mocked for feeling like an extended episode of the series instead of a film worthy of a cinematic release, and for its failure it is still wrongly assumed by many to have been the series' Franchise Killer.
- Padding: The imagine spots.
- Sequelitis: The Nickelodeon version aka the first seasons is highly praised and almost all fans agree it's good. Then the ABC/Disney version broke the base but there are a considerable amount of fans who praise it. Last, the movie goes even further to the point where it is criticized by almost all fans.
- So Bad, It's Good: For some this movie has so many bizarre things about it it falls under this.
- Ugly Cute: Herman.
- The Woobie: Roger's robot, whom the movie is rather needlessly cruel to at the climax.
