I don't love it or hate it. They've had some good bits, some bad bits, and quite a few meh bits. Honestly, I prefer Odd Future's music, but they seem to be having a good time doing what they're doing regardless (and seem to be pretty successful at it), so more power to them.
Also, I don't think they're trying to be the 'next Jackass' (despite the fact that the show is made by dickhouse) - their style is more sketch comedy than 'pain game'.
