Any actor that shows symptoms of TDS.
Sadly this, and I'm not even a fan of Trump! It's just the fact that they pile on just to virtue signal, and even then- who are virtue signalling to???
Anyway, Ellen Degeneres I can't stand (even though she is in a film I love that seems to be forgotten call EDtv, and she was pretty good in it. It was before she got her TV show and thought she was an untouchable human being).
Kumail Nanjiani. I cannot see how this guy could possibly star in anything. How did he become famous? Sucking up to the right people? Either way, he shits me.
Jim Carrey. I used to LOVE Jim Carrey, and still love Dumb and Dumber and the original Ace Ventura. I can watch those films and see a guy willing to give it his all without being a pretentious prick. Then he went all crazy and I thought, fuck you. Just completely turned me off him and I can't watch anything he is in now (I must admit I though he was OK in Sonic).
Brie Larson. Just cannot stand the smug attitude.
Quick edit- The Rock Dwayne Johnson. I've yet to see him star in anything even remotely considered half decent. The (VERY) poor mans Schwarzenegger.
There are many others that I just can't think of at the moment, but these were the 1st that popped into my head.
