Scooby-Doo 2: Monsters Unleashed/YMMV

These things about  are subjective - not everyone will agree with all of them.
 * Author's Saving Throw: James Gunn made the sequel closer to the cartoons by having the monsters come from the cartoons and that the film felt more like a Scooby-Doo film than the first one. Also, the bad qualities of Mystery Inc. are mostly gone.
 * Big Lipped Alligator Moment: The potion scene where Shaggy and Scooby drink potions is quite wacky.
 * Ensemble Darkhorse: The Tar Monster and the 10,000 Volt Ghost are considered the most horrifying monsters, which make them stand out.
 * Ham and Cheese: Peter Boyle, Seth Green and Tim Blake Nelson sure had some fun in the movie.
 * Hilarious in Hindsight:
 * Another WB film (Teen Titans Go! To The Movies) would have the main villain disguise himself as a woman and again in Scoob!.
 * The Skeleton Men could be prototypes of the Minions from Despicable Me because of how stupid they are and they comically speak gibberish.
 * Memetic Mutation: "I think Coolsville sucks!" The quote can be used if something is taken out of context.
 * One-Scene Wonder: The Cotton Candy Glob is hard to ignore since he was eaten by Shaggy and Scooby so quickly.
 * Sequelitis: Many critics at the time of it's release considered it inferior to the 2002 film.
 * Signature Line: "I think Coolsville sucks!"
 * So Bad It's Good: It's not that good, but it's a good kind of bad.
 * Surprisingly Improved Sequel: Many Scooby-Doo fans consider it better than the 2002 film because it is more true to the cartoons.
 * Took the Bad Film Seriously: As with the first film, Matthew Lillard did a convincingly great job as Shaggy.
