Entertaining and thought-provoking, even moving

Rating: 7/10 (9 March 2014)

"Beowulf" is an animated 2007 film version of the epos featuring Ray Winstone, Anthony Hopkins, Angelina Jolie and Robin Wright Penn. Although it's a "cartoon" it's the equivalent of an R-rated picture with brutal violence and openly sexual situations & dialogue.
The film has the same characters as the epic poem -- Beowulf, Hrothgar, Wiglaf, Grendel, Grendel's mother and the dragon -- and the three Acts split between Beowulf's fight with Grendel, Grendel's "sea hag" mother and the dragon; other than this the film deviates from the poem. Needless to say, don't watch if you're a Beowulf purist.
However, if you don't mind the animation or the re-imagining and enjoy sword & sorcery adventure like Conan, you'll likely appreciate it. It's both entertaining and thought-provoking. I recommend watching this version back-to-back with 2005's "Beowulf & Grendel," which is a live-action version with Gerard Butler and Sarah Polley, shot on the gorgeously bleak landscapes of Iceland.
The message of this animated version is that the reality behind the story is much different than the legend because it has been embellished over the years. Some reviewers complain that Beowulf isn't a genuine hero, but this isn't true. He's a bold warrior who takes on the gargantuan and intimidating (not to mention UGLY) Grendel NAKED and somehow defeats him! He then goes on to lead a mighty Nordic kingdom for decades to come. If this isn't a hero, what is? Okay, so he exaggerates his past exploits and has a weakness for babes, what else is new?
I should add here that, not only is this a beautiful film to look at, animated or not, it also has an excellent epic Viking-ish score by Alan Silvestri, highlighted by the main title ("What We Need Is A Hero") and the two versions of "A Hero Comes Home" (the first is the shorter version sung by Robin Wright-Penn whereas the second, sung by Idina Menzel, plays during the end credits).
***SPOILER ALERT*** The rest of this review explores the meanings behind the story and gives away important plot elements
I'll be honest with you, although I was entertained the first time I saw "Beowulf" I came away from it thinking "Huh?" This version makes King Hrothgar the father of Grendel, and Beowulf the father of the dragon, making it absurd in a what-were-they-thinking way, but also creative.
Viewing it a second time, I was intent on figuring it out and gleaning the moral(s) of the story. The main lesson, aside from the one noted above, is that new political leaders tend to make the same mistakes as past political leaders, so new leaders should be careful or they'll experience the same pitfalls.
Other points include:

The mistakes of your past will inevitably come back to haunt you.

Apart from redemption, the "sins of the fathers" will cast a pall over the family or community and eventually come back to bite 'em (literally!).

Even the greatest heroes are human and have serious flaws.

Deal with your past mistakes (sins) or the guilt & shame will drain the life from you and your environment; it'll also make you wish you were dead.

Offer a man unlimited power, wealth and fame and he'll likely go for it no matter the cost, selling his soul to the devil, so to speak.

Men are easily entranced by a beautiful babe, regardless of how obviously impure her intentions.

A beautiful woman can turn a man into a loaf of bread.

The importance of saying you're sorry and forgiving; the importance and ultimate triumph of love.

Some things to think about: Why is the dragon one-and-the-same as a noble-looking gold-skinned man? Does this signify he's a cross between malevolent blood and noble blood (mother and father respectively)? Is he able to morph back-and-forth at will? Is the golden man his spiritual side and the dragon his dark side?
Some criticize that Beowulf is not a Christ-figure, which isn't accurate. Although late in the story Beowulf mourns that there are no heroes in the new Christian era, only "weeping martyrs," ironically he goes on to be an obvious type of Christ by sacrificing himself for the people of his kingdom (the world) by slaying the dragon (the devil). Keep in mind that, according to the Bible, all things were created through Christ, which would include the angel Lucifer, who later devolved into Satan. Likewise the golden man in "Beowulf" was created via Beowulf and is later revealed as a hideous dragon.
All human types of Christ are flawed because humans are flawed, even ultra-heroes like Beowulf, which -- again -- is one of the main points of the film. Hence, Beowulf's perception about "weeping martyrs" is faulty and can be attributed to his fallen condition when making the statement. Later, he rises out of the ashes to slay the dragon and sacrifice himself for the people. Right before doing this he declares his love for his wife and asks her to forgive him for his past failings.
One scene had an impact on me. Years after becoming a king, Beowulf boldly confronts a defeated Frisian warrior who mocks him on the Nordic coastline. Beowulf commands his men to step back, discards his sword and challenges the warrior to kill him (at this point the Frisian has picked up his battle axe). Weaponless, Beowulf yells at him with every fiber of his being, "KILL ME! DO IT! KILL ME! KILL ME!" Why does Beowulf do this? Is he invulnerable and, hence, has no fear of death? No, the ending proves he's wholly mortal. Actually he's so burdened by guilt and shame that he no longer even cares if he lives or dies. This is reality, my friend. Who would have expected this in a "cartoon"?
