My problem with the mentioned lines is that they fall short. A secondary problem is the cinematography. This is, perhaps excuseable because it used gameplay footage -- but that just makes it a design problem over poor execution.
Back to the writing...
"Death's design will be complete" -- either, this is misguided spice -- or too indirect a mention to the true demigods behind the absolute.
"Bow before me, bow before the Absolute, bow, bow" -- lack of motivation that isn't "I'm brainwashed". This makes him seem too generic to be *the* villain. My problem is less what is here than what isn't.
"But you have something he doesn't, allies worth having",
A statement as grand as this has to be earned. It cannot be when we don't even know who these allies are.
"Together, we will strike down the absolute"
Unnecessary, should not be mentioned twice in such a short clip.
Altogether, seems hastily put together. Has the making of a checklist of what needed to be said... rather than something the creator enjoyed? Maybe I'm totally off here, but the lack of real emotion makes me think the grandiosity is a coverup.
