New movies. Same thoughts as the on the old ones. Get a good writer, director, actors, come up with a good story, you have a winner. Let some fanboys who like to see lots of gore loose on 'em, you don't get the audience.
Alien was scary, and aside from the chest-burster, not all that gory. Good date movie.
Aliens was a better picture, and for me, the acme of the series. Cameron is a better moviemaker than anybody else who has laid hands on the franchises.
For me, Predator was okay. P2, not so much. AvP? Less said the better. A3, I've mentioned, didn't work for me at all. A4. Meh.
We all have our choices for our own reasons, them's mine.
As for Predator POV, my daughter and I did a little of that in AvP, and fans seemed to like it. We're weren't supposed to go there, they didn't want us to, but we did it anyway and they decided they liked it.
I offered to try a book with that kind of POV, and they decided against it. Their toy, they get to make the rules.
