Is Rune: Viking Warlord for PS2 good?

I saw on ebay this game new and really cheap, and while it sounded good and the salesman said he tought it was good (never played it but his friends said it was good) i was thinking of buying it, however i read a review about the game that sucked, but you guys know that sites that review games always really harsh and most games don't get over 6, which in most cases is acceptable. So well, should i buy it? Is it any good?
