What PG is the movie Is my a vampire?

There seems to be a misunderstanding. There's no movie titled "Is My a Vampire".

Perhaps you are thinking of:

* "Is My Teenager a Werewolf?" - This is a Disney Channel Original Movie with a TV-PG rating.

* "The Vampire Diaries" - This is a popular TV series with a TV-14 rating.

* "Twilight" - This is a popular movie series with PG-13 ratings.

Could you clarify the movie you're asking about?
