All About Steve is a messy assemblage of clumsy sight gags, winking reaction shots and disingenuous populist genuflection to the idea that there's no such thing as normal. We all see a little bit of Mary in ourselves, don't we? Don't we?
There's no footing in reality. Nothing about it feels authentic: not the blathering Mary, not the lifeless secondary characters, not the bromide-happy dialogue or the plot that twists less often than it spasms.
The movie is trying to show the power of words and that there is no such thing as a "normal" person. It should garner a boatload of nominations for Razzie Awards that are given to the worst movies of the year.
