Yep, it doesn't have much to do with Ozzy-era Sabbath, so if that's all you're looking for, you can pretty much disregard it.
But if you like a wider palette of metal, this is really a great disc. The opening four songs are all top notch metal and cover a pretty wide territory. Anno Mundi may be the most 'progressive' song Sabbath ever did. The Lawmaker is fast, has a killer chorus riff, and sounds a lot like something off of Holy Diver, actually. And The Sabbath Stones is a classic, with a pure doom riff changing to a fast triple time outro.
There's a silly little synth orchestration in the middle, then you get another killer pair, the quiet, pretty Odin's Court flowing directly into Valhalla, which is upbeat and almost anthemic, with a catchy chorus you'll scream along too.
Surprisingly good production and high re-listenability value; I've got a lot of spins out of the disc and still enjoy it a lot. More than anything it reminds me of Savatage in the Zak Stevens years, so if you like that kind of metal, definitely check this out.
