Sucker Punch, Does it really suck?

Sucker punch IMDb

The first time I saw the movie Sucker punch, I thought, this movie looks cool, but nothing makes sense or has reason in the plot. What is real? What is a dream? is it just a big waist off money an talent?

Every review I ever read said, this is totally bullshit! the only thing this is the perverted childhood fantasy of the director (Zack Snyder) on the the movie screen. And I was totally confused, because very I was sure that this could not be the reason this movie was made.

After some research I found an article that linked me to this video on youtube, wutch stated that zack Snyder confirmed was an accurate analysis of the movies plot.

Afterwards I have had argument countless times with people about the plot, so I wanted to make my own summary of the plot to clear up some issues people have had:

The main character speaks to the audience at the beginning: "This is my fantasy guardian angel, sometimes a little girl, sometimes an old man. They help me through life".
When the "angel" goes to the mental institute, she sees the main character on the stage, where she just re-acted the opening scene.The "angel" goes through all the same problems that the main character did. Only this time as a mental journey, through layers of fantasy.
the main character has been under pressed by men all her life, and that's why she imagine her angel living in a brothel. Later she makes her "angel" take control over the situations where usually the men are the dominant one. The "angels" "dance" is her mental way to be free from a mans dominated world, but she just re-appears in another fetish mans fantasy world, but this time she has weapons to take  the control herself. The old man that appears is just another "angel" that tells her to be strong, and take control.
In the end the main character (not her fantasy "angel") is the one that is able to escape mentally from the brothel, the world of being seen as an object.In the mental institution, her "angel" ends up the same way as she did, mentally gone, no men can harm her or tell her want to do. The movie ends with the Main Character basically finishing with the words: "now it's your turn to fight for who you are, and don't be suppressed and used as an object by others"
