It's come to be in the great cinema spectrum that Pixar makes cinema and Dreamworks makes cartoons. These days, I prefer the laughs, and "Monsters vs. Aliens" is a cracking animated comedy that takes wonderful care of its characters and pace, presenting a brisk, frequently hilarious romp that rarely pauses to reflect. The simplicity is refreshing.
"Monsters" only stumbles when trying too hard to either be cutesy (it's the second animated film in under a year to use the "Axel F" theme as a punchline) or satiric (Stephen Colbert as The President invites uncomfortable silences). When back on solid ground, the film is a blast as a straightforward, silly-hearted adventure, literally bursting through the screen to entertain as vigorously as it possibly can.
