From the Ottoman perspective?
Must be for a Turkish audience.
Otherwise, I can't imagine why anyone would find sympathetic the point of view of people who ended a 2300 year old civilization (older if you count Greece), destroyed the great Imperial Library of Constantinople, thus burning the knowledge of the ages, raped (including small children) and enslaved tens of thousands, and desecrated and/or destroyed two of the holiest churches in all of Christendom filled with the accumulated artifacts of 1400 years of faith including the remains of all the apostles and every Roman Emperor from Constantine the Great to Alexius Komemnos.
A conquest that ultimately culminated in the second worst genocide of the 20th Century and the worst on-going case of ethnic cleansing (Greeks and other Christians from Asia Minor) in the world.
I must say it isn't for me.
