I don't know what I want

So I used to think that I wanted halo 4 to be more dark and gritty, even more so than reach.

But I watched some halo 3 today, and the brightness and everything just really appealed to me, it was very interesting. I want the colorful game that is halo, but I also want it to be dark and scary sometimes.

What do you guys think?

Is it possible to have both, or do we have to pick one or the other.?
