Metacritic score seems strange
I know Metacritic uses a weighted average, but I still don't see how they came out with 19/100 for this film. Austin Chronicle and The A.V. Club both gave the film a 0, but the other fifteen reviews range from 20 to 60. The average of the scores would be 28/100. Are the Austin Chronicle and The A.V. Club's ratings so valued that their scores can drag it down that much? The only other thing I can think of is that Metacritic deduct more when a 20/100 relates to a 1/5 review where 1 is the lowest score a film can receive from that publication.
