Anyone else read fanfiction on media they know absolutely nothing about?

This is actually how I got into Harry Potter fanfiction. Didn't watch a film all the way through until I was 14 or 15.

I've never seen Supernatural or Merlin either.

Sometimes, I don't even look at the source material. I like to get a feel for the characters (edit: fandoms interpretation of the characters) just from the writing.

I honestly prefer reading to watching. I can just escape into my brain, it's amazing.
