Rest assured, Friday the 13th will never have a "final chapter," and after a 3D installment, the only way to one-up the series is with the twin appearances of a pervy Corey Feldman and the inimitable Crispin Glover. The formula is tried-and-true here; Jason died in part three, he's revived in the hospital here, and heads back to the lake for more slaughtering. Most of the cast is phoning it in, at best, but Corey and Crispin (watch him dance!) make for at least passable diversions.
