I haven't played Bioshock Infinite, so I can't comment on his review one way or the other. However, it's worth mentioning that Tom McShea doesn't assign the scores to his reviews. He's stated a few times that the other reviewers read his review and then determine the score from that. Make of this what you will.
If that is true that is the stupidest system I have ever heard of. It is his review, he should pick. Especially now that they are doing the multiple reviewers thing, it is no longer some overall site score.
