this is not some muslim thing or some historicall thing, belly dancing in king's haram is not some islamic shitt
I have watched this movie, and i found it pretty good, I don't care about if they got all historical facts correct or not because it's a MOVIE! I didn't see anything that would classify this movie as bad.
Besides the point of making a movie without plastering it with propaganda is to make it attractive to watch for a wide public audience. It's a movie where you'll grind your teeth and clench your fist, but there are also times where you rejoice.
IF you have watched The Lord of the Rings, Avatar, you'll be the biggest Fu**face for not watching this movie. Because it almost doesn't have any scenes where you'll feel like puking out of boredom. (I say almost because I don't recall any scenes).
One thing you should know though is that the movie doesn't focus on Sultan Mehmet completely because like all great rulers he stood back and gave the orders, and it was his loyal troops who carried out the orders, and good commanders.
Oh yeah the CG, animations etc. are pretty damn good, especially considering this being one of the first movies where the cast, crew etc. was so damn large. (many ppl and other stuff).
