I’m sinking into my second viewing of Leaving Neverland (HBO,3.4 and 3.5), and there’s just no denying the drill-bit honesty of this film…no denial, no diminishment, tough as nails.

The millions who are still glomming on to the myth of Michael Jackson — that half-magical, commercially formidable, white-sock superstar aura that has persisted and expanded since his death on 6.25.09 — these millions who are still feeding off Jackson are about to experience a profound kick in the head from this four-hour doc.

What I mean is that the Jackson-guilt denialists are finished. Jig’s up. Once this four-hour doc hits HBO, forget it.

Leaving Neverland is a talking-heads horror film — an intimate, obviously believable, sometimes sexually explicit story of two boys — Wade Robson and Jimmy Safechuck, now pushing 40 — who became Michael Jackson’s special “friends” — i.e., lovers, masturbation buddies, fellators — while their more or less oblivious parents went along, thinking that the relationship was more of a kindly innocent bond.

Wake up: Jackson was a finagling fiend, a smooth predator, the kindest serpent.
