Some of the riffs work very nicely, as the emphasis is kept entirely on straightforward metallic crunch. The resulting simplicity can work both for and against the album: when the riffs hit home, it seems to make them all the more enjoyable; but when they don't, it renders the entire track uninteresting, as it has nothing else to offer. The balance of enjoyable versus passable tracks may depend on quite how "metal" you're feeling at the time, but the ratio is generally acceptable. Simple, unpretentious fun, but not something you will be very likely to keep spinning after a while.
