Quotes in IMDB- Beowulf (2007 film)
I am Ripper... Tearer... Slasher... Gouger. I am the Teeth in the Darkness, the Talons in the Night. Mine is Strength... and Lust... and Power! I AM BEOWULF!

 With the golden glow of fame, fortune, great sex, and enormous power in the guy's face. THIS WAS THE POINT OF THE WHOLE MOVIE, children, that the seduction of power, etc., can not be resisted by even the most heroic... proven by two kings and the one just made, likely, also.
And, the seducer can not be killed.
This film is not some Hollywood action thriller with Bruce W. closing up with the NECESSARY happy ending. THAT would have ended with, "bitch." BEOWULF is of a higher order of cosmology and awareness of real human nature. This is a good illustration of the difference between film art and film junk.

Good ending and let the viewer decide the outcome. It makes you wonder if the tale ended or if men still sell there soul for power :)
