Insanely Beautiful

As much as I love Arrested Development it never rings true to me when Mae's character is referred to as bland, forgettable, plain, etc.
Is it an inside joke that I'm not getting, hiring a beautiful girl to fill such a role? Or do people really see her that way?
I think she is one of the prettiest actresses working today.

Just because your truth isn't the true truth, doesn't mean there is no truth, Ruth.
