Best Snyder movie so far. Sadly it is deeply misunderstood. Movie is way more deeper and complex than it looks like on first glance.
People don't realize Sweet Pea is the protagonist, Babydoll is a figment of Sweet Pea’s imagination. Babydoll does not exist. Babydoll's story is Sweet Pea’s story. Sweet Pea was sexually abused, killed her sister and is in psychiatric hospital in therapy. Babydoll is Sweet Pea's avatar. Way of dealing with grief, with guilt, and way to manage her current situation and overcome it. Babydoll is also Sweet Pea's guardian angel.
Sweet Pea is the only fully rounded character, other girls represent aspects of her psyche. Babydoll represents strength and courage, Amber loyalty, Blondie fear, and Rocket represents guilt. In the third level reality her psyche fights for the things to get her free from her current state. Second guardian angel (the Wise Man) guides her through. To fully recover she needs to get over her guilt (Rocket dies as a symbol), also other girls represent things which she needs to leave behind to fully recover .
Babydoll is one of those things. She is the fifth thing (“The fifth is a mystery. It is the reason. It is the goal. It will be a deep sacrifice and a perfect victory.”). Lobotomy of Babydoll represents Sweet Pea’s mind of taking control. Sweet Pea needs to sacrifice Babydoll to be “cured”. Escape at the end is a symbol of that process of being cured. That’s why the driver is the Wise Man, he guides her further.
Sucker Punch is Sweet Pea’s journey from “madness” to “sanity”. Movie is philosophical / psychological investigation wrapped in a special effects action-fantasy. As the movie changes realities (mostly in the third reality), Snyder uses more fetishized image of the girls. He uses clichés and cluttered iconography (nazi zombies, sexy schoolgirls). It is a way to detached and disconnected characters from second reality. Second reality, the brothel, is the “main” reality. In which everything happens.
