Really? I don't see Meryl Streep as a persona, but I guess you could call her that. I think I don't mind Meryl Streep for a very dumb reason - because my mother liked her, and I almost always took my mother's preferences, however slight, when it comes to celebrities and accentuated them. We've diverged paths since but the Streep thing is one I remember from early childhood. It's the reason I still like Jack Nicholson even though rationally I think, um, not that good... because my mother liked him. It's sad really.

I guess my #1 most hated persona is Julia Roberts. But it's hard to know how seriously she's taken.
