I don't know if I directly agree with you, but I do generally agree with you that the movie was not as good as it could have been.

It kind of felt like a Jackson Pollock painting. All of the parts and pieces were there in roughly the correct amounts, but it was so scattered and all over the place that it was hard to make any sense of it, except the very thinnest of plot lines.

I will say it was entertaining, and it was beautiful, and it was definitely a visual cornucopia of special effects and events.

But as far as the core of the story, I feel like they didn't nurture it enough, and they didn't focus on it enough, and they didn't bring it to full flower before finishing the movie.

They were the consequence of a mutagenic virus in modern times

why are you being downvoted? I didn’t see the movie, but it sounds like a solid review (I’d still watch it)
