Does anyone else despise 'black' church services?

im a Christian, and im not racist. the reason i can't stand even watching them on tv is because there is no stability in their sermons so far as i've known. i think it is insulting to God to helm His church and minister to His people by screaming and pacing and jumping from scripture to scripture, having the sizzle, but never the steak. Christians what are your perceptions of this?
