A bunch of inaccurate information.
Constantinople was renamed Istanbul in the 1930s... and was founded about 330... and was taken from greeks in about 190 so when events occur in 1400s, and the historian says people have been trying to capture it for 1700 years and that the city is now named Istanbul, We can't trust anything.
We did watch the whole series but the most severe obvious errors were in the last episode by the historians. we questioned battle reenactments (we were wondering about crossing moat)
it would have 3 stars but glaring errors by historians and otherwise high rating causes adjustment.
