Huh- big difference between the endings. I prefer the original version for several reasons, not the least of which that it actually fits with the story elements that were dropped in the movie but which the theatrical ending completely ignores (that being that the vampires were more intelligent than just being animals). Thematically, though, I think the theatrical ending of him dying fits better with the character's personal story arc and the title. Maybe if they'd combined the two in some way it would have been better.
I'm still miffed that they thought that cgi vampires would be better than having actual people play the parts, though.
