The games are very flawed, but they have awesome cutscenes and a killer soundtrack. Except for Zelda's Adventure. That game looks horribly boring.

It's not that scary when you know they're friendly. It can be pretty unnerving when a door opens by itself,or when you see a shadow figure,but when you know you're not gonna be harmed. It's alright.
I believe in ghosts,because we have 5 spirits in our house. They used to open doors and move things. Just wanted us to acknowledge their existence. Nowadays,they're pretty quiet.
