i think LXG would have been better should it remain loyal to the original graphic novel, where, amoung other things, connery would have been a opium addict.
i believe it's the same graphic novelist who illustrated the book that was adapted into the movie From Hell. While FH wasn't especially gory, it very much retained the grit from the graphic novels as it was translated to screen.
LXG looked cool on screen, but i don't think it kept much in key other than its comic book style action. Stephen Norrington is also a notable director with a very stylish ... style.
I don't take summer action flicks seriously, neither should you. They're meant to be fun, not fundamental.
