The Ugly Dauschund is a children's film. The Care Bears in Wonderland, Ferngully, Once Upon a Forest and The Rugrats Movie are children's films. I was all of six. Allow me two paragraphs to make an assumption about the frame of reference of the reviews. The very first film review I ever had published was a take on a re-release of Walt Disney Productions' The Aristocats, for my High School newspaper.
Cartoons are the chief culprits, and they bear the full brunt.
Some people carry these feelings their entire adult lives, and I believe it is precisely this syndrome that prevents animated films from ever being taken seriously in film classes and the upper strata of film commentary. I usually illustrate this theory with the sad tale of the day my Aristocats story broke. Lets face it, the humor in the Star Wars films is not exactly to be found in witty intelligent banter to begin with. I remember the first big laugh of the original Star Wars, and it wasn't a reaction to anything spoken, it was to the sight of R2-D2 falling down. Kids laughed their heads off, and more than a few adults did too.
