that said, the kink is even better if it works within good characterisation and is believable in the character interaction.

When the characters are too OOC I stop seeing the originals and if it is good simply enjoy it for that and not for the characters I adore.

The interesting thing for me is when the writer has a different view of the characters from mine. So they are writing with what they perceive as canon characters but it makes me wonder if we were watching the same show. Everyone views the characters from their own cultural and personal backgrounds and can interpret things very differently from another.
At least it keeps the fandom alive and active!
