I've seen several people pointing out that MB gave it a 6 out of 10 (a generally positive ranking) and trying to figure out why everyone is on him about "hating the movie".
Personal anicdote - I am a big time Tolkien geek (admit your inner geek, and embrace it). Coworker is likewise quite the Tolkien fan. We both had gone on Opening night to see Fellowship of the Ring. During lunch the next day, we talked about all the things they left out, changes made, and why we didn't like those. Someone in the break area said, at the end of lunch "So you hated the movie?" When we replied "No, we really liked it a lot" they replied "But you just spent an hour listing everything you hated about it..."
Thus my main issue with this review; the first part was a 'before' bit saying how he was totally prepared to hate this movie. The large majority of the second part was spent detailing everything he hated about it.
In doing so, he drowned out his own message that it wasn't a total bomb. If you think they got 60% right, and spend all your time complaining about the other 40%, you lead people to form the conclusion "Wow, he really hated that"... and having said so much, when you try and throw out something that seems to contradict most of your message (I'll give it a 6 out of 10), the easiest thing for a viewer to do to reconcile the conflict is disregard the smallest part possible. That would be the bit at the end where MB says 6 out 10.
So, I think that, while MB may have thought the movie OK but not great, he's managed to convince everyone he'd prefer to burn the print than admit he'd seen it.
That is why I think it's a bad review; not his opinion, but the fact that he seems to so horribly miscommunicate his overall view (an OK film) by ranting so loud and long on the parts he didn't like. To be honest, skip the last 30 seconds, and I'd have thought he gave it a 2 out of 10 max...
