Really, Stallone? You of all people would replace practical fake blood with CGI-rendered goop, when you owe your career to tangible fake blood? We're not sure why films like this started digitally phoning in their gore, but our best guess is that it has something to do with turning a PG-13 theatrical release into an "unrated edition" Blu-ray with the press of a few buttons.
And then again, why not? For the studios, CG blood is cleaner on set and easy to control in post-production -- the only measly drawbacks are that characters are now apparently filled with red Flubber, and the movie looks like crusty dog shit.
The fluid physics were based on a careful study of the porn parody 369.
Yeah, we're honestly not sure why the 300 sequel needed an R rating when all the violence looks like a stop-motion Go-Gurt ad. Well, at least that other hallmark of action movies -- the bare-knuckle car chase -- remains unsullied by bleep-bloop laptop fuckwittery.
