Surprised by all the poor ratings given apparently by a bunch of wildlife/wolf/survival experts! Guys, this is a Hollywood movie! Let me emphasize - a movie. All this analysis on how much a wolf weighs and how their behavior is incorrectly depicted... please stick to NatGeo or Discovery channel programs and stay away from fiction! Going by the logic and reviews, Spielberg's 1975 classic 'Jaws' should be given just a star or two as it has a highly inaccurate portrayal of sharks. But surprise surprise, it's 8+ on IMDb! Wow how did that happen?! I enjoy a movie for the entertainment value it provides. And if the film can hold my interest for about 90 minutes, I'd say it worked. The Grey definitely worked!
