I just watched a week old episode of The Walking Dead last night, which is a show on the US network AMC about a group of people trying to survive in a post-zombie apocalypse world (based on a graphic novel, ironically). One of the characters was walking the perimeter of the farm the group is staying at, and came across a cow that was ripped open stem to stern, bloody guts all over the ground. It was at that point a zombie attacked him, and ended up eviscerating the poor guy before the group put him down out of mercy.
Now, prior to watching this series, I always though of AMC as pretty tame. Even so far the most you really see is blood splatters when a zombie is shot or when a survivor gets bitten by one of the zombies. It is cable television, admittedly, but the amount of gore between the cow and the guy the zombie attacked surprised me. So yes, I agree with Luc that the public audience in general may be more desensitized (it's spelled with a z you silly brit!

) to higher gore levels, but it still turns my stomach somewhat. (note: I'm not a fan of the horror genre, and movies like Saw turn me off to them even more)
Putting that aside, to me there's a difference between "gore" (severed body parts and the like) and "buckets of blood" (see Army of Darkness or anything by Quentin Tarantino). I'm ok with the buckets of blood approach, which aside from ghost girl is all we've seen so far. But if guts start pouring out of someone like in the opening of the movie Ghost Ship I might get a little squeamish.
