Dunced Reveiws

Anyone notice your reviews getting the "not helpful" nod disproportionate to what you may think is the quality of the review. Am sure some reviews can be contraversial and some piss people off cause they liked the movie but there is some wierdness afoot when an apparent attempt at a thoughtful and good review gets multiple negs. Just wondering if others have noted this. Seems strange, but may be the paranoia induced by poor choices.
