I've got a lot to say about this film, given the paper I wrote on filmic adaptations of Beowulf, but I'm behind on my thesis, so I'll let a brief review suffice for the time being. Hopefully, time will allow for writing a conclusion to that original paper in the near future, to strike while the proverbial iron is still hot.
This revisionist cinematic version of the epic poem stays surprisingly true to the heart of the heroic ethos. While many seem to have missed the subtlety of the story amidst the spectacle of 3D CGI, puerile humor and over the top gore, Gaiman and Zemeckis have raised complex issues surrounding the idea of macho heroism, deconstructing without destroying it. My guess is the story is getting lost in the midst of the spectacle, which is unfortunate; this is the best Beowulf brought to screen yet, paying tribute not only to its original source text, but to the postmodern theories regarding Grendel and Beowulf as two sides of the same coin.
