do you mean CGI?
hmm, sin city what do i think?
i think it has an absolutely stellar cast, and at least tries something a bit original in trying to bring a noir graphic novel "to life"
however, it is certainly full of itself, and i don't know about anybody else, but i find with Sin City (as with 300 also), that watching this film, with the lack of real sets and completely digitised environments, that after a short while it gives me a really bad headache
