Dubstep is just really boring, I think. Everyone seems to use the EXACT same bass. Synth, rhythm, everything. And that whole "wubwub" thing might be alright if it wasn't used so damn much. But as it stands, I have not heard a good dubstep song yet. Even the ones that I might otherwise like are ruined by the vast amount of music that uses all the same sounds and techniques. I like heavy bass, but not the kind of bass that is synonymous with dubstep music nowadays. I like more traditional bass sounds like a string bass or a bass guitar.
Although I can't really fault people for liking dubstep, because I like stuff that's just as widespread or "speaker abusive".
