Most blues suck - some is good in small doses. "Red House" by Hendrix i think is very good - he doesn't play the typical boring crap with the typical boring tone, and the recording is unique compared to other blues songs, i think it worked. "Yer Blues" and "For you blue" by the Beatles i also like, probably because they recorded over 100 songs and only 2 were blues songs. I think the real issue is if an artist plays only or mostly blues, then its boring. Personally i think Jazz is usually just as bad, its more interesting but it is basically crap. John Scofield is amazing at scales, that is great, the songwriting is non existent though, its just a boring long jam session. It would be more pleasing if somebody incorporated Jazz into a songwriting format of some kind. Phish was ok at that, not really Jazz though. Country too sucks most of the time, sure there are exceptions. Rap almost always sucks. Pop is mostly crap. Punk is mostly crap. Metal is mostly crap. Electronica is mostly crap. I can't think of any genre that isn't mostly crap with exceptions who do something good within it. So yes blues suck in general, as with everything else, i suppose blues being so basic makes it difficult to do something fantastic with.
