I would guess he does, since the trailer upset him as much as it confused and/or unsettled all of the other Eisner fans (who are not unobjectively loyal to Frank Miller) who have seen it.
Besides, even if he wasn't familiar with Eisner's work, what does that have to do with this trailer... in spite of some commendable moments (which I praised in an earlier post) it reeks of Miller cliches.
Here's a thought... since you claim to be an Eisner fan... if he WASN'T familiar with Eisner's Spirit... do you honestly believe he'd get a good idea of what Eisner's work on the character is actually about?
I saw the trailer with a friend who isn't into comics last night and his response was "wow, it's a movie about sex".
Here's what an uninitiated viewer would learn about 'Eisner's' work from that trailer... There's a man who dresses up in a mask (but we don't know why) and looks for women to have sex with. He is running around in dark alleys with a gun (but we don't know why) looking for more women to have sex with. Even this Ellen woman, who seems to be some sort of positive influence on the Spirit is just looking for kinky sex ('Keep the mask on") so she can "break all sorts of rules" with him.
Then, the womens' pimp shows up ( I guess he's their pimp... he's dressed like one in some scenes and is mad at the sex guy in the mask) and is asking why the sex fiend in the mask is so into women.
And then, the sex addict in the mask floats around in some smoke with a sex woman who wants to be with him forever...
Oh, and the sex guy in the mask shoots a gun (but we don't know why)... but, I think I already mentioned that...
Seriously, I liked a LOT about the trailer (see my previous post), but I actually know these characters. If I didn't know what this trailer was for, I would think it was a mainstream release soft core porn film with some sort of gun toting nut in a mask. Honestly, the trailer doesn't even tell you WHY he's pointing a gun at a naked Sand Saref... who is she? Is he a rapist? What is his character about...? Other than sex?
Put yourself in the shoes of the general audience, who don't know Eisner from Adam... and you get reactions like "Wow! It's a movie about sex!".
