Well most of the reviews I've read/heard pretty much go in line with what I thought on the very first hearing.
Drawn out, half-arsed and lack of quality hitters.
After a few more listens though, I'm drawn in to it more. I'm liking the overall dirtier sound of the album and it does actually flow really well. It's not their best effort, but other than the latest Kings of Leon album (and still not sure on Metallica's new one yet), there's nothing produced in the past 18months that is any better IMO.
I think reviewers these days (goes for video games too) are far too sloppy and opinionated. They should be as partial as possible, but they are not. A listen or two and the review is written. This is why I don't pay any attention to them, as they are mostly just idiots with a job they don't take as serious as they should.
