From its first moment, reality is flexible and the lines between actual threats and hallucinations — the product of head trauma — are fuzzy. The bad news is that “HIM” has far more ideas than answers; it lacks both a cohesive philosophy and a satisfying narrative conclusion. (It certainly has an explosive and gory conclusion, but those elements are often inserted into films in lieu of a tightly wrapped narrative.) But Isaiah White is equally parts Jake LaMotta and Pennywise the Clown, a vicious trickster who manipulates the audience as well as he manipulates his protege. The film is worth seeing for Wayans alone — provided that you’re prepared to witness a lot of blood on the pigskin.
