For the most part, I don't like it, or perhaps 'get it' either. I used to listen to BBC Radio 1Xtra's Daily Dose of Dubstep just to see what all the fuss was about and I found most of it to just be 5 minute tracks of really repetitive synths and anti-climatic drops. However I did find some tracks that had really dark, sinister tones to them, interesting melodies and deep, low-end basslines - that's the sort of thing I like in any genre of music and luckily for me I have a stereo system that really gets the most out of bass-heavy music, much to the dismay of my neighbours. I guess the point here is that while metal is my favourite genre, I do branch out if I find a certain track interesting.
I guess I should mention Korn's latest album, The Path of Totality, since they decided to fuse heavy metal with dubstep/electronica with the help of Downlink (who I've looked into further and actually don't mind), Noisa, Excision, Feed Me, 12th Planet, Kill The Noise, Datsik and *shudder* Skrillex. I've got to say, I was very skeptical when Korn first announced they'd be making a metal/dubstub crossover album but it works really well.
In a nutshell, I'm not really a fan of dubstep, but if it's done well (i.e not just 6 minutes of wub-wubs and horrible electronic screeching) then it's okay. Skrillex certainly isn't a good example of what it should sound like.
