I expect most of us have got a 'Jaco', i.e. somebody whose popularity/reveredness we just do not get. Yours (OP) is Jaco, Spiders' is fusion as a whole, mine is Les Claypool. Oliver's language analogy was spot on; you don't speak Jaco and I don't know a word of Claypool. Doesn't make it crap, it just means that we don't get anything from listening to it.
