Fictional to begin with, doesn't even relate to reality. The movie depicts alauddin khilji as villain and a monster, but it's hard to believe that kind of king is even possible. You'll find this movie glorify rajput and may portray muslim as bad, barbaric. Also, khilji is treated with disrespect throughout the movie by rajput but infact khilji saved our nation from mongol invasion (note that mongol invasion never leaves remains of previous civilisation). Still, from fiction point of view its watchable even if it shows altered history.
