Remember you are reading mainstream reviews for a very "core gamer" title. If you are usually in line with those reviews then yes, perhaps you should be wary, but if you're not then I would say disregard them. A good way to tell would be: did you love Oblivion? If so, maybe you should be wary.
That said the DKS version of Divinity 2 supposedly makes the game much more easy to play for mainstream gamers, so maybe you should read some of the direct feedback on that.
