Complex says: The Devil knows what he’s doing. Whenever Hell’s leader possesses a poor soul in a Hollywood movie, his victim is often an attractive young lady, like in the inferior sequel Exorcist II: The Heretic. Grown up into a button-cute 18-year-old, The Exorcist’s little tyke Linda Blair used her carnal powers to lure the sequel’s priest into a false sense of eroticism. Any good man of the cloth knows, though, that clergymen must forbid all physical desires in the name of God’s work. Just imagine what would’ve happened if a little boy were possessed.
