I Need to Start Reviewing Movies Without Seeing Them

If any of you have read a review about Green Lantern then you probably believe it's the worst movie since that one Sandra Bullock movie she got a Razzie for. I clearly saw another movie titled Green Lantern starring Ryan Reynolds, because there's no way every major critic out there could be that wrong. Well, there is one way: suppose the film wasn't available for viewing early enough for them to make their deadlines so they based the reviews off of the previews and/or poster. Or possibly their own terrible screenplays/fanfics based on the series.
