As far as your interpretation goes...
I'd be more than willing to watch it a second time. I've said all I wanted to say last week [http://www.escapistmagazine.com/forums/read/6.387238-The-Big-Picture-You-Are-Wrong-About-Sucker-Punch-Part-One?page=4#15462682] on the subject.
That being said, Upon watching this week's argument, I can sort of accept your argument a little better than the first week, where it felt like you were trying to play "Bob Chipman versus The World", but this week felt like maybe there is some validity to your statements.
I have maintained that Zack Snyder is a smart guy (He has to be, as far as music video directors turned Movie directors go), and as such, he probably thought about some things more than others (Most writers do that anyway, best of intentions in the beginning and all that), and this side of the argument seems to sound like things Snyder might have thought about whilst writing.
I hate being this guy, I really do. Much as you said you wanted to like Expendables II, I wanted to love Sucker Punch, and I wanted to be the guy who could defend it amongst a handful of film people (But I only know about three in my hometown, so the Escapist fills in the rest), but it's terrible that I have to follow the crowd and go, "No, I agree with everybody else", because nothing can convince me of it otherwise.
I do the same thing with Popeye, the Robert Altman film. I Love that movie, and it sits on an even 5 out of 10 on IMDB, but the fact I can convince people of its brillance and maybe be the only guy who can do it is kind of rewarding in its own way. Sucker Punch, I can't convince even one of the bigger film buffs I know that Zack Snyder is a smart guy because he gave all the girls nicknames (which I maintain is more memorable than average names, the reason we remember The Goonies is because they all have nicknames), and he looks at me quizzically every time I mention it.
Sucker Punch was a beautiful looking motion picture, but it had little, if nothing, to keep me interested in its characters, which for me, is the kiss of death in most movies. The girls were bland, and I hate saying that, believe me.
However, the next time it is on HBO and I have two hours, I'd be more than willing to sit down and watch it again, with your argument going on in my head.
