"Monsters vs. Aliens" is possibly the most commercial title of the year. How can you resist such a premise, especially if it's in 3-D animation? Very readily, in my case. I will say this first and get it out of the way: 3-D is a distraction and an annoyance. Younger moviegoers may think they like it because they've been told to, and picture quality is usually far from their minds. But for anyone who would just like to be left alone to see the darned thing, like me, it's a constant nudge in the ribs saying never mind the story, just see how neat I look.
