If you receive a call from area code 207, don’t pick up. Toss your phone, change numbers; or, smarter yet, drop it and RUN! The now-adult members of the Losers Club, the group of rag-tag middle-schoolers terrorized by the maniacal clown Pennywise in Stephen King’s horror-thriller “It,” do none of those things. They answer, only to be greeted by an eerie voice urging them to “come home.”

Thus begins “It Chapter Two,” a funny, gross and indulgently long slog through nearly three hours of convoluted clown carnage adapted from the second half of King’s 1,138-page best-seller from 1986. It’s (much) more of the same as the Losers Club reunites in Derry, Maine, for a rematch with Pennywise, the killer clown they seemingly vanquish 27 years ago as confused adolescents unable to face down bullies, overbearing mothers, abusive fathers and other hurdles in growing up. The most interesting part of Gary Dauberman’s script is seeing how the events of their youth informed their adulthood.

The reason they’ve returned to the scene of the crimes is because of a pact sealed as kids. Beverly (Jessica Chastain) is in a bad marriage; Bill (James McAvoy) is a best-selling author who can’t write endings and still stutters; Mike (Isaiah Mustafa) never left Derry; cherubic loner, Ben (Jay Ryan), is a hot architect; germophobe and hypochondriac Eddie (James Ransone) is a neurotic risk-assessment agent; and wisecracking Richie (Bill Hader) is a successful stand-up comedian. As for Stanley (Andy Bean), he doesn’t make the trip back for reasons the film will ultimately reveal.

Structurally, Dauberman’s script reprises their traumas and tribulations from both their kid and adult perspectives. That’s six sets of perspectives - plus extraneous material - resulting in a wicked long movie. And I haven’t even mentioned the terror scenes, all rote horror schlock: from jump scares (OK, I flinched), to loads of gooey blood and the slurpy and squishy sounds of death. Props to the sound editor. It’s a violent, gory screamfest that does nothing but make you laugh.

When the adult Losers are on screen, getting reacquainted and falling back into the rhythm of their old friendships, the movie soars. You want more of them, especially Hader. The “SNL” vet flat out steals the movie. But director Andy Muschietti can’t seem to make up his mind which direction he wants to go: the human drama or the supernatural horror? When all else fails, the director relies on Pennywise (played with glee by Bill Skarsgård) and his mouth full of piranha teeth to jump out of a closet, box or appear in a window or mirror. Even that eventually yields diminishing returns. You might be led to believe that the movie is terrifying. It isn’t. Pennywise comes off as too cartoonish to induce any lasting frights. The real scares are confronting our own demons. Bloody, silly and overwrought, “It Chapter Two” is certainly down to clown, but I was decidedly not amused.
