Ultraman Movies: Future, no future, and not past?

I watched a few Ultraman movies. And I'm putting my scattered thoughts all in this post. Spoilers abound (even for the end of Dyna and sort of for Mebius and Cosmos).

Ultraman Saga and The Ultra Galaxy movie: ( Mirai; Future Earth. )

And, since I'm too lazy to make a separate post, I might as well have this tagged on, even though I wrote about this movie way after I watched the two movies above and it has nothing to do with them. Wait, that isn't true. Ultraman Zero is in it, so I guess it has something in common with the rest of the movies, after all... (Oh, Taro and Mebius also appear, sort of. ^^;;; Yes, I mean the fusion. I would scream with joy if it's them in the flesh.)

Ultraman Orb the Movie: ( I actually like this movie more than I made it sound under here. Lots of random spoilers. )
