On a completely different tack, I'm going to go with things that bug me based on popular entertainment:
Justin Timberlake as an actor - He's like the Madonna of this decade. That's not a good thing.
Alexa Ray Joel - For those who don't know, this is Billy Joel's daughter. A few years ago, she had a song called "Notice Me". Which probably says all you really need to know about her ability to hold an audience. That, and the fact that daddy never taught her not to sing through her nose. It's very clear that someone's trying really hard to make her happen, because she just released a cover of "Just the Way You Are".
I watch Once Upon a Time (don't judge me, I used to think it was a lot of fun). In the first season, they introduced Belle. Rumplestiltskin was The Beast. OK. When she showed up in Season 2, almost every time she showed up in a scene with Rumple, it was to remind the audience that they were supposed to be shipping that. Which, as attractive as I find both actors, they have zero chemistry, and the relationship dynamic is gross. I finally gave up after an episode or so ago when a plot point hinged on "the strength of their love". Really, writers, stop trying to make it happen.
And this is my feminist soul snapping into action after Miley Cyrus called herself a "feminist": Pop culture, stop trying to convince women that empowerment comes from sexing yourself up. In the real world, if you try and "sexy" your image up, people think all you really want others to notice is your sexual attributes to cover the fact that you're a bimbo (see: Palin, Sarah) and you don't get taken seriously. Yes, feminism IS about choice and this is not about "slut-shaming" anyone. BUT, if you're dancing around in flesh-colored latex while not making some justifiably artistic statement about it being satire, you don't get to slap the word "feminist" on it just because nobody else is willing to tell you otherwise.
tl; dr on the last one: Ask any leading feminist if Miley's doing anything more revolutionary than what Madonna did thirty years ago. Unless, you know, you want to turn sexuality into something gross. In which case Miley is a pioneer.
