Not to be mean, but ...
Why does she have fans? I'll concede she's pretty, but other than that, I don't get it. I've seen her in plenty of films, but other than Third Person (which I thought was great, though I know a lot of people didn't like it), I can't say I've thought much of her performances.
Just curious. The question pops into my head every time I see someone write "I'm such a Mila Kunis fan" -- the latest was while browsing the American Psycho 2 board -- not done with this film yet, but it seems really terrible so far (about a half hour in).
If you happen to be Mila and stumble across this, please don't take this personally. I'm not trying to criticize you, rather to understand your appeal so I can better appreciate your work.
