Got around to watching it, and I'm sold. It looks like there's going to be solid character dynamics, a good amount of blood, and the Predators look good. I'm also glad they haven't spoiled some of the crazier stuff from the script in any of the trailers yet, I still want some visual surprises. I hope we eventually get some tie in between the Uograde and the Super Preds, I agree that the last shot looks really Super Pred-y, especially the forehead.
The vagina joke worked for me, it was bad just like Black's jokes in the first movie.
