why this movie is awful?

Fist of all I really appreciate to screenwriter and directors that make movies about Persia history while they can't take pictures in Iran but unfortunately most of these movies are made with strong prejudice!

why this movie is awful? because:

1.Fake history; Ibn Sina was died in 58 years because disease not suicide! he was always in traveling and writing and he had physical feeble but he had no time to cure himself. finally he gave up and said to his friend "I prefer a short life with width to a narrow one with length". Ibn Sina did autopsy on a dead human body when he was young! Ibn Sina wasn't a person that just quote previous scientist sentences! contrariwise one of his bad personality was arrogance to previous scientists like Plato.
other things in this movie is true, like burning books.

2.It is not bright at all; Rob Cole traveled that long way to learn from Ibn Sina, the famous physician that cured cataract disease and many other diseases like that Jewish guy said to him, but what we see from Ibn Sina in this movie? nothing! the awful part is Rob Cole can find people death with a sixth sense or something! so this is a realistic movie? the answer is obvious.
