Of course gore is more important than plot.
At least in a slasher, or AVP type movie.

There really isn't much more you can do with the two characters.

I would love to see them let loose on an empty planet.

Plots are for different types of horror movies.

And I love them (Seven was all about the plot).

But AVP is more about inventive kills,
and intense violence and gore.

Don't mess that up with some silly love story.
