I'm thinking of watching The Originals before watching Vampire Diaries is that fine or would it be confusing?
It will be slightly confusing. Luckily not in such a way that the show doesn't make sense at all. I'd say you'll be fine(granted abit in the dark on certain characters who make an appearance or get mentioned in the show). But you should watch TVD first (at least the first four seasons) if you want to know everyone and this show a little better. 😎
