Other than fulfilling the studio’s Equity mandates (at last black girls the world over can finally “see themselves” possessed by demons & some kind of African voodoo(?) priestess is brought in as an assist because apparently there aren’t millions of black Christians the world over) this adds nothing fresh or interesting to the franchise unless you consider 2 possessed girls - as opposed to 1 - interesting. New shocks are obviously off the table but suspense is missing as well. Returning characters are only there to give a momentary thrill to old fans, and then escorted away from the main story. A cash grab, and a Woke one (guess who the weak link will be).
