At first glance the similarities between Lindsay Lohan and Charlie Sheen seem to trump their differences. Both were wildly successful in their own rights -- she in teen flicks, he in sitcoms. Both have addiction and relationship dramas, both have daddy issues and both screw up. A lot.

But while Sheen seems to be encased in kryptonic armor protecting him and his bank account from all of his misdeeds, Lohan can't even keep a movie gig, and no one wants to pay her to do much of anything, even sell tights.

What gives? Is it a male/female thing? The age difference? I don't think so. Sheen has simply made better personal branding choices. He gives America the product they want.
