Oh man, I'd like to make a fanvid or an AMV one day. I too have lots of Opinions on them though, very similar to yours!

There is one (1) fanvid I am okay with using original sound effects/few words of dialogue. It's for Hannibal so TW for gore, blood, violence, cannibalism etc. Glitter and Gold. And it's so short! But pure editing perfection IMO. Everybody else can go home and mute their source clips, please xD
