That Marmaduke makes a point of farting when Phil and Debbie kiss sums up the film's level of appeal.

Spectacularly sentimental, full of ridiculous computer-animated action, and makes sure its animals are a good deal less pallid than the humans on view.

Better than Cats & Dogs, but praise hardly comes much lower.

Marmaduke is exclusively manufactured for child use, and analyzing it would be equal to discussing the design of a rattle. [Full review in Spanish]
