Zack Snyder’s Sucker Punch (2011) is a visually stunning story about a young girl who is institutionalized by her abusive stepfather. As a method of coping, she envisions an elaborate scheme with a goal to free herself from the institution.
Beware, the following text may potentially contain spoilers.
This movie appears to be deeply misunderstood by a lot of people, and since it contains an infinite amount of visually appealing scenes, nazi zombies, monsters and lightly dressed women, overlooking the complex layers of the story may very well just be a unconscious decision.
The key here is that Babydoll is not the protagonist of the movie, but a figment of Sweet Pea’s imagination and doesn’t really exist. Sweet Pea was the one who ended up in therapy at a psychiatric hospital after being sexually abused and accidentally killing her sister when trying to defend her from their stepfather.
All other girls in the brothel were just different aspects of Sweet Pea’s personality, and Babydoll is the "fifth thing" to overcome – The lobotomy of Babydoll was a way for Sweet Pea to let go of her illness and fight back, leading to her imminent "escape", or being cured.
The "second" reality (the brothel) was in fact reality as Sweet Pea visualized it, and an obvious clue is where Blue Jones was stabbed in the shoulder which was present in the "first" reality as well (the hospital as we would see it).
Score: 7/10 (Good)
