Why did Obito survive being crushed by giant boulder?

*Stayed dead, you mean. He was considered dead for all intents & purposes, until Kishimoto decided he was not.

By plenty you mean the few Crack Theorists who were spouting bullshit that had, and still has, no basis in canon that was not a last second asspull.

It is one of the many things I will never forgive Kishimoto for.

can we talk about the ending instead? I couldn't even watch the last few episodes because of how ugly both the story and character design had ended up.
