I found the score consistent with the text and thus I am fine with the review. Also, I didn't liked much FFXIII and the review was helpful to what I should expect from XIII-2 if I ever try it (which is very unlikely at this point). If anything, I think some editorial overview could help the writing here and there but it is a minor problem.
The reception of XIII-2 is a much more interesting subject. Many review sites and magazines consider it somewhat better than its predecessor but, despite that, they are giving lower scores. If anything, it shows how susceptible is game journalism to hype and tradition as it is clear now that XIII was overrated by most reviewers.
