What about Kevin Hart's comedy is good? Like how is saying things loud funny?

I saw him perform once at the Roast of Justin Bieber. He was annoying most of the time because he kept shouting and getting annoyed at ISIS jokes, even though nobody else said a thing. And yeah, he was very loud and kept having fits of laughter at his own routine. I personally think he should stick to scripted movies and television because it suits him better, but that's Just my opinion :)

Everybody has their own taste in comedy, just because you don't think he is good doesn't mean that he is bad.

Your question is funnier than Harts career
