How do you know that?

Well, the Vampires and the Lycans didn't start with one big coordinated dance how they are all friends now. So the war is still on.

If it's possible, I think that they should probably make at least 2 more movies: one to set up the events for the Final Battle; and another film to conclude the series. The titles could be: Underworld: Fall of the Vampires; and Underworld: The Final Battle. What do you think?

With no Michael, no point

Well, maybe the creators can find a way to bring Michael back, either as a ghost; or as a hallucination of Selene's designed to give her strength and encouragement. Maybe.

I won't be pleased if they do either. Either he comes back alive or I don't want to see a continuation of the films. He was too big a part of the series.

Well, as a member of the Corvinus Family, Michael's blood is very special. If there really is a way to harness it; then maybe it can be used to bring him back in some way.

There might

Yes and no. I was disappointed with some of the creative choices, particularly with the way they killed off Michael. An implied offscreen death. He deserved much better.

Other than that, I was reasonably satisfied. I just think Michael should have survived. Maybe extend the post final battle scene to reveal that he was still alive and Eve had found him, and the final scene is all three of them reuniting.

That would've been a much better ending.
