Beware the beginning. You may just think you’ve accidentally sat in on the theatre playing Shrek IV, but you haven’t! While the start looks better suited to a Disney Anime or a next gen Final Fantasy, the graphics do certainly get better.
While reviewers like to compare this movie to 300, I will say that beyond them both being based on graphic novels there is no comparison. 300 was amazing, and so good that you had to look past any historical inaccuracies (and consider it a fantasy), while Beowulf at times just got silly.
See this movie with someone who has a sense of humour, and who isn’t looking for a brilliantly written tale. See it with someone who enjoys a decent action flick, and can laugh at the sometimes comical scenes that Gaiman tries to pass off as dramatic.
While Beowulf is a good movie, it certainly was no 300.
