A tiresome, repetitive film that is in no way going to hold up to repeated viewings, neither for kids who think flatulence is hilarious nor young adults desperately seeking camp.
Ebert & Roeper:
The acting is stiff, the story lacks all trace of wit, the sets look like they were borrowed from Gilligan's Island -- and the CGI Scooby might well be the worst special-effects creation of the year.
It may ... work as a jaunt down memory lane for teens and young adults who grew up on televised Scooby-Doo shows or reruns.
Robert K. Elder,
Scooby-Doo knows when to take itself seriously and when to laugh at itself -- even if its audience isn't laughing along at every gag.
New York Times:
The obnoxious special effects, the obligatory outbursts of flatulence and the incessant, so-five-minutes-ago pop music on the soundtrack overwhelm what is left of the scruffy, dopey old Hanna-Barbera charm.
By embracing the original series' tacky elements and inserting just enough self-mockery to avoid smugness, the movie manages to fulfill basic expectations.
Throws scraps to different audience constituencies and ends up with a muddle.
The novelty of seeing these characters on the big screen is occasionally fun, but this Scooby-Doo is no Great Dane.
Globe and Mail:
A frenetic, cluttered $100-million worth of haphazard plotting, fart jokes, computer-generated monsters and visual chaos.
The source material here is flimsy to begin with, and neither Gunn nor Gosnell seems to know how to flesh it out.
The movie drags, and the occasional bursts of mirth and self-referential humor can't save it from bogging down.
I feel no sympathy with any of the characters, I am unable to judge whether the live action movie is a better idea than the all-cartoon TV approach, I am unable to generate the slightest interest in the plot, and I laughed not a single time.
Any thinking, reasoning human being with an appreciation for cinema would reject it as the vilest trash. Needless to say, it cracked me up the whole way.
San Francisco Chronicle:
Do you really want to spend money watching what is essentially marginality, or would those dollars be better used to see a better film or even buy a good book?
Lillard gives the flick its manic energy, and the rest of the gang holds its own.
Not that the TV show was so riveting, but most of the half-hour plots were more compelling than this lackluster warmover.
Much funnier than it has any right to be, and filled with just enough inside jokes to please longtime fans of the cartoon franchise.
As this movie knows what it is, Scooby-Doo's a relatively painless 85 minutes.
