Colosseum
Overall we learnt quite a bit, but it was quite a mixed bag of generalisms and grandstanding by several historians who went way beyond the history. All emperors had access to use the Colosseum to advance there standing with the people of Rome, not true, the Colosseum typified Rome not true, circus Maximus was the main draw in Rome. Gladiators were trained slaves not wholly true many freedmen to fame and wealth and chose to be gladiators. The Colosseum was how slaves became freedmen, not true Romans free thousands of people each year and even married them.
Several episodes dragged terribly and just kept repeating the same stuff, the worst one was the Martyr.
Overall I liked it but the historians irritated, one man moved his hands matching every syllable, this is like a text message in capitals it shouts at you. For me this is a 6 outta 10, it could have been great but turned out pedestrian.
