There's a great scene in Wallace & Gromit: The Curse of the Were-Rabbit, where the titular menace comes rampaging into a garden festival. The owner of the 'Garden Supplies' stall slaps up a hastily scrawled 'Angry Mob' sign over the word 'Garden', and quickly starts selling pitchforks and spades to the townsfolk. The whole scene is probably less than two seconds long, and by the time you've registered the gag, it's already moved on to the next one. The whole film is like that- one gag after another, which somehow forms a single entertaining entity.
W&G may not be the best film I've seen this year, but I certainly haven't seen another which has caused me to have a permanent goofy grin throughout the entire running time (which is short, and was preceeded by a quaint but not wholly successful Madagascar short). There's actually so many gags, some of them so well hidden (the newspaper headlines are particularly hilarious) that you'll never get them all, and indeed you'd have to have an encyclopedic knowledge of film lore to get every single reference (although the Watership Down reference is insanely brilliant) that they throw in. Some of the gags are inspired, others are lame, but even these are given a sort of joke-from-your-dad charm by the delivery of the fantastically good-natured characters.
"So the Were-rabbit can only be killed by a gold bullet?"
"Yes. It has to be twenty-four......carat!"
"Get out of my way, you idiot!"
The constantly consternated Gromit is the star of the show, forever trying to keep up with Wallace, who seems to bumble through the film unaware. It's amazing how much expression they can give Gromit just by manipulating his one big plasticene eyebrow. The endless stream of bunnies who populate every frame are another great highlight, making cute "weee!" noises whether they are being stuffed into drawers, sucked up by vaccuum cleaners, or indeed think they've been shot and are heading toward the light.
Wallace & Gromit is just plain good fun- go see!
Oh! And watch to the end of the credits for one last cute gag.

This movie is also great in that no effort has been made to clean it up or smarten it or change it so that an American audience will get it (aka Fever Pitch/The Perfect Catch). It works because it is not pandering to an audience but just having a good laugh, quite often at it's own expense.
