Maybe it's an uncanny valley thing, but I hate the fake emotion and attitude in this demo. I'd much rather it tried harder to be bland. I want something smart but not warm, and I can't imagine being frustrated by "lack of drama".

It doesn't sound like a neutral, boring voice. It sounds like an overly dramatic person pretending to be a robot.
That's precisely what it was ordered to do.
