If he had gone from catatonic to menacing, I would have liked it waaay more.

Also, and I'll keep saying this, the movie should have had another big twist at the end, where that building he kept talking about actually does blow up. I mean, he's the VILLAIN. After showing the world that superheroes exist, he should have done something truly diabolical to prove that the world also needs them.

Just posting a bunch of youtube clips before he died was not a satisfying end.
