Amy Schumer - I guess I maybe don't get it. She wasn't bad at all in Trainwreck. But the stand-up? OMG, just so unfunny. From her content to her delivery. Basically any female comic that spends 75% of her show talking about her vagina and how dirty she is, isn't my thing. Worthless.
Will Ferrell - Well, besides Elf, which might be in my top-10 comedies. His whole thing is just too far over the top. Too corny, too unfunny. Anchroman might be the dumbest film I've ever seen. I get why people like him.
Jim Carrey - Okay, maybe Anchorman isn't THE dumbest film I've ever seen.
John Leguizamo - Decent actor, but unfunny attention-whore. Took Billy Crystal's act and ruined it.
Kevin Hart - There are two sides to this one. First, I think he is an absolutely hilarious comedic actor. I'll watch a Kevin Hart movie anytime. But his stand-up is among the most unfunny stand-ups I've ever seen.
Rob Riggle - Might be the most annoying human alive.
