Just in case you thought it might be good....

It's not. Son of the Mask reviewed by The Onion:

The law of diminishing returns dictates that sequels to bad movies are the worst movies of all, because the producers are not only working to rebottle the original non-magic, they're inevitably doomed to come up short. Even by those standards, Son Of The Mask is more handicapped than most, since 1994's The Mask was a vehicle tailored to the specific talents of rubber-faced fartsmith Jim Carrey, who's wisely keeping his distance. But as with Dumb And Dumberer, another sequel to a Carrey hit minus its principal cast, New Line owns the property and has retooled it for the thumb-sucking set, so parents are advised to bust out the emergency Ritalin. It's hard to believe that beings as young and delicate as children are the target audience for such a frantic, retina-searing assault on the senses, but as pure visceral experience, Son Of The Mask borders on the experimental.
