Hmmm... I can't really say anything about Clannad. I know it's supposed to be all feelsy but one of my friends showed me another show that he said was like it and I was incredibly bored with it.
Though, I don't know anything about Death Note either.
Dammit, that probably didn't help at all :<
You'd probably have to mail death threats to every world leader, kidnap at least half of their families, kill half of the half you kidnapped, burn down at least one major city in every major area, and basically tell your armies that every citizen that wears a certain coloured shirt is a rebel and needs to be killed immediately
yeah I don't remember him doing that
