I like screaming, but if there aren't any other vocals in there as well, I find it really boring. But if you have a screamer and a vocalist going at the same time, or at least just in the same song, it can sound really nice. Most music with screaming is ... well, monotonous. The drums are monotone, the bass is monotone, the vocals are monotone ... the guitar usually isn't monotone but it doesn't normally have a catchy tune either, it just seems kind of random and all over the place ... and it just bores the hell out of me. That kind of music, I don't like. But if you have a catchy tune or a strong rhythm, and there's a screamer in there too, then a lot of the time it comes out great.
