The World Wars
Episode 2: "A Rising Threat"
The Good: The paths to power of Hitler, Roosevelt, and Churchill were well done besides the fact they stumbled on chronology for Churchill. The various battle scenes were another great part of this episode like the previous one. The opening scene of the Stock Market crash and then the 'Night of the Long Knives' were very well done.
The Bad: The various chronology errors and double backs, which went hand-in-hand with asserting that political or military decisions were based on leader's opinions of their opposites in enemy nations (save for Churchill's warnings about Hitler). Asserting the Emperor Hirohito was more politically involved then he likely was.
The Ugly: The repeat of awful retelling of the Communist takeover at the beginning of the Stalin segment. Patton is completely ignored this entire episode even though he is one of the characters featured in the title sequence.
No Opinion: The path and motivations behind the Japanese attack on Pearl Harbor seemed off, especially their economic/military strategy in Southeast Asia and the Pacific. However I'm not too sure if it's part of the chronology errors listed above or just wrong history.
