As someone who isn't an expert in WWII and has just recently became interested in the topic, I found this to be very informative. It did seem to drag on at times (especially the last episode), but it was worth it as I left knowing much more about Hitler than I did before. I was a bit disappointed at how misleading the title was however. They don't really go too deep into his personality but instead just showed a few speeches he did and gave a quick reason why it connected to the audience. It's really more about the rise and downfall of Hitler, not an in-depth analysis of his charisma. It seemed like a tacky thing they tried to plug in to try to differentiate it from all of the other documentaries on Hitler.
The footage they showed was rather interesting. They did have some cheesy re-enactments that weren't necessary, but it was more of a background thing so I wasn't too upset. The music however, was rather obnoxious at times. They played the same music between their transitions that would blast for a few seconds. It was rather over the top at times.
Another thing I disliked, was that the series seems to repeat itself. Episode 3 repeated so much from episode 2, that I thought I was watching episode 2 again on accident for the first 10 min. They also throw in their charisma "analysis" which gets repeated over and over but doesn't add too much.
Overall it is a decent watch, especially for those who are beginning to learn more about WWII. You won't learn a lot about Hitler, but it gives a decent overview of the rise and fall of him. I do understand why WWII buffs would be disappointed in this however.
