I think being creative, witty, or just knowing the aesthetics of telling a story has a lot more importance to writing a review than knowing how to partularily write grammatically and phonetically well. Anybody can write a dry, bland, text book (synopsis/technicals/supplements) reviews ala DVDBeaver or Blu-Ray.com. Those are a dime a dozen. What keeps readers coming back for more is something fresh, unique, maybe find a certain "hook" to tie in with your review.
Very few (if any) of Bleeding Skull's reviews are that long nor are they written with any sort of strict grammatical correctness. Yet, many of the reviews can have the reader in tears from laughing so hard. They are entertaining. Period. So entertaining, infact, they have a book in the works.
