Stop with the conspiracy theories.
First its CBM, we are not even suppose to link to them because they are full of a lot of things, and news is not one of them lol.
Second, if WB was really being biased with it, I'm sure they would have done something more for GL, which landed at a 26% and was one of their big expensive films. It's not being biased. Reviewers say what they think and they compile it, its not some mystery.
EDIT: And Parker Wayne I've seen them do this before WB bought them, just email them and tell them the mistake, I'm sure they will fix it. If it indeed becomes a problem people won't go there and they will lose business. But I've seen that stuff where sometimes they count it and they don't, and I know some that have emailed them about it. I think some are making this a little more then it is I think.
