I haven't read the various articles by the multitude of companies
that worked on the film, but I'd be most interested in both
the makeup and special effects (visual effects is the CGI, special
effects are the physical gags) to learn if they were using
chocolate syrup or karo syrup for the blood or the relatively
newer concoction that apparently looks fantastic but tastes
horrible, so the actors despise having the blood capsules in the
mouth.

My problem with going to a film with gore is that I'm more
interested in the technology making it happen, so there's
almost no impact for me.

Now, doesn't that just ruin the gore for you?
