Melissa McCarthy does that for me. It's getting better, but for the longest time I'd see an interview with her about some project and she's funny, charming, intelligent, and convinces me to check it out. Then I would watch the thing and it's like "Haha fat girl poopoo fart." .
The only two things I can say that I enjoy her in are Spy and Only Murders in the Building.
In both cases the rest of the movie/show carries her but she doesn't actively make them worse like she does with 90% of the stuff I've ever seen her in...
