How gory is the movie "Watchmen"?

I'm a big superhero movie person, but I've been reading that Watchmen is very gory. I'm wondering just how gory. I'm pretty squeamish . I can watch people getting shot and stabbed that's no problem for me. I've seen movies like The Mist, which I know is not anything super gory, and I watched that guys arm get ripped off by a lion in the happening, along with people get their throats slit in Sweeny Todd , which I know was very unrealistic. I watch medical shows, such as House and bits and pieces of Grey's Anatomy as well. None of those things bother me terribly. So how would you say the blood is in "Watchmen " in comparison to the things I've listed above. Please and Thank You.
