For some reason Sucker Punch was in my Netflix DVD queue and arrived this week so I watched. My thoughts are pretty much the same is when I saw it in the theater back in 2011.
I'm not the first to make the Inception comparison, I also found it in io9's roundup of 2011 movies. While io9 savaged Sucker Punch I'm not as critical of the movie. It's not a great movie and probably not one I will own on DVD/Blu-ray (though I do own Watchmen and 300). But I found it entertaining and am particularly fond of the zombie World War I scene.
The issue of Zack Snyder's idea of female empowerment has already been flogged to death. But I get the concern that his version of Wonder Woman may be Baby Doll or Sweet Pea with dark hair.
