This review's title is a description of my reaction to this movie. After seeing Blade, I now have to fight the urge to describe most other movie-productions in 'degrees-of-Blade' (since I wish to call myself a writer, I need to fight most of my convenience-urges!).
First, there's its source-material: It's based on a comic book, so it's instantly attractive. The comic-book itself was based upon the storied history of vampirism, which is fascinating. It's a combination of the old and the new, the ancient and the futuristic ... which brings me to my main point.
The main antagonist was a vampire who was using a computer to translate the ancient texts of The Book of Erebus ("The Vampire Bible"). That made me think of a couple 'lessons to be learned' there ... from a couple of the ways the antagonist could have lost.
It made me think of the Christians' interpretation of Biblical text (mostly the atheists' interpretation, which is guided by "reason" and not by 'Faith in Infinite Intelligence'). See, one must interpret Biblical text with The Writer's Plan in mind ("Infinite Intelligence's manifestion by humanity" is the stroke of The Writer's Pen).
For instance, some atheists make note of God's apparent promotion of slavery (in the Old Testament), and ask, "If any intelligent person will tell you that slavery is wrong, how can you claim to serve an unchanging God who promotes slavery?"
I reply, "How can you claim to be free to live without paying homage to Queen Elizabeth II if any intelligent person will tell you war-against-government is wrong?"
I'll answer both questions, "Because slavery and war-against-government are not present when we reach the goal of The Writer's Plan!" The Book of Erebus (with a slightly different Writer) may not have been written to extend the life of the Vampire Race, so perhaps it should not have been translated by a machine built for purposes of such extension.
But don't deny the power of the new! That's another lesson contained in this story; just because something never worked in an old environment doesn't mean it won't work in the new! And it was shown in Karen's use of new blood-medicine to work on a serum that eradicated vampires with their very-own blood.
The difference between her serum and the translation of The Book of Erebus was that the serum was actual material made with its own substance; the Book was simply the scrawlings of a character's imaginings about an imaginary imagination.
NOTE: Contrary to the MARVEL-origin, there is no 'detective' or 'Dracula-descendent' in the movie ... just didn't want readers to get their hopes up.
