That show on Netflix is a lot of just conspiracy and dramatization to make it all really entertaining and interesting. He did die in that bunker. I forget where but either I watched a video or read an article about it that the soviets buried his body there and about a week later can back and dig it up to bring back to decide what to do. They then decided that instead of keeping it and having some really fucked up place for people to try and come see it that they just wanted it buried and some with since he was such a horrible person. So they took his remains and had two guys go into some woods to bury it. Then they thought that wasn’t a great idea cus eventually someone would find it so they dug it up in the middle of the night and cremated his remains then scattered them so they could never be found. I really wish I could find the video or article because it was so informative and interesting. I’ll link an article tho that shows that the few pieces of his remains the soviets kept so they’d always have some proof is actually his bones. French study on Hitler bones
