I hate when that happens.
Granted, she's been kind of pulled back a little recently, but it's like when a certain celebrity appears in something that's really, really successful, all of the sudden, they're EVERYWHERE, in EVERY new movie that comes out, and/or making guest appearances on EVERY popular show on TV, popping up randomly in any commercial you may see, being featured on all kinds of webseries and podcasts, etc.
Mila DOES have a bit going for her, I agree, and like I said, she hasn't really been seen too much within the last year or so, but for a while there, she was EVERYWHERE, and she had become quite overrated. Another problem though is that there will be a little lull in which we actually don't see them for a little while, then all of the sudden, boom, they start being shoved in our faces all the time all over again... and as I said, Mila's not the only one: Steve Carell, Neil Patrick Harris, Lea Michele, Jane Lynch (and I actually used to like her), Rachel McAdams, Amanda Seyfried, Joel McHale, and Jennifer Lawrence is now actually complaining about it happening to her, saying all the fame and attention she's getting is taking a toll on her and she's on the verge of having a mental breakdown.
I still agree that Mila's a pretty good actress, likeable, and hot, so she has that going for her, but Steve Carell's acting is ALWAYS so stiff and wooden, NPH's schtick of "Look at me, I'm a big celebrity, but I try not to let my ego get the better of me because I'm a big celebrity" got really old really fast, Lea Michele is kind of a narcissist, Jane Lynch has the same problem as NPH, Rachel McAdams kind of does the same kind of movies over and over again like Jennifer Aniston does, Amanda Seyfried can't seem to do one movie without taking her clothes off for the camera, Joel McHale is just annoying, and I really don't see the appeal of Jennifer Lawrence, so I honestly don't know what it is about certain celebs who are always given the spotlight like that.
