I wonder if this happens in reviews of other mediums? Greg McElhatton over at Comic Book Resources has posted a review of the latest Batman comic, #697 in which I think one sentence was about that particular issue. The rest was a rant about the story line that ended with that issue and praise for the artists growth. The only reason I know that Mr. McElhatton enjoyed the book was the 4 1/2 stars at the top of the review. So do you recall a movie or book review where it is almost entirely about the creators other work? I suppose it does happen.
