PG-13

The Harry Potter franchise had gotten by with a PG rating up to this point, but no more—we're in firmly PG-13 territory now, friends.

Apparently, when kids start dying, that seriously ups the scare factor (and, as a result, your MPAA rating). Also, there's a decent amount of focus on sadism, evil, and sociopaths (Exhibit A: Voldemort, Exhibit B: Barty Crouch…you get the picture).

So, definitely prepare yourself for a more adult Harry Potter experience, and give your five-year old cousin a few years more of Frozen before jumping into to The Goblet of Fire.
