I saw it.
What exactly about it was thought provoking? People keep saying that.
Anyway, my impressions:
Skillfull editing.
Great costumes.
Abysmal story (especially when it starts nearing the end, when it turns to fantasy more than anything, and the overly predictable course it takes).
Abysmal script (right from the get-go when he utters his first soliloquy, I see that old habits of Matrix 3 die hard when you need to find complex words as to try and obtuse the viewer - Mission:Failed... "Insipid").
Good acting execution, the actors squeezed the most out of it, especially Portman, she could play anything with a good amount of credibility. Skillfull.
Special Effects were as per usual predictable, although I believe they stole the knife thing from somewhere (I guess D&D games - not exactly proficient in the whole "blue halo around blade", but that's where it screams from - like in the Lord of the Rings 1 with Frodo's auto-detecting sword)
And that's it.
Rather... not worth my time. I didn't need to see the movie to know that Hitler is bad and that Homosexuality is good. I can see that whenever I turn on regular television.
My final review:
**** this ****.
