I'm interested in seeing the film, but it really irks me when people mess up the classics. The Beowulf story is a great story. If you like it, then tell it. Tell it like it is. If you don't like it, then write your own story, with your own characters, and then tell that story.
Twisting "Beowulf" around so that the hero is a bad guy tells me a lot about how leftwing Hollywood is (not that I didn't already know it).
Well there’s something to be said for interpreting a classic work. Slavish, impersonal literary adaptations are the stuff of Masterpiece Theater. At least Zemeckis seems to have brought a point of view.
