I've actually seen more negative reactions to the reviews from haters than from fans. Hell, I've even heard people claiming that Bethesda bribed everyone to give good reviews since Skyrim can't
possibly be better than Morrowind or even good at all.
On the other hand, a few reviewers really don't know what they're talking about and some clearly aren't cut out for anything more complicated than Call of Duty. One reviewer said he got lost often and took points off, another claimed to have beaten the main quest in two hours (and this was supposedly a plus, which is even weirder when another review said the MQ took 65 hours), etc. Most reviews are decent however. In any case, being an Elder Scrolls fan who loved Oblivion to death and doesn't have any unrealistic expectations I'm sure I'll enjoy Skyrim more than a lot of the reviewers seem to have enjoyed it.
