Unnecessary sequels aren’t anything new. We ended up with three “Toxic Avenger” follow-ups, three “Wild Things,” and a second “Road House,” so the appearance of “Bad Kids of Crestview Academy” isn’t completely surprising. It’s a continuation of “Bad Kids Go to Hell,” a 2012 chiller that I’m not sure anyone actually watched, but apparently some degree of success was reached, spawning a new adventure in the world’s least secured school with a fresh group of obnoxious characters. The material is based on a graphic novel, giving it a shot at irreverent fun, playing with slasher film conventions and teen sarcasm, but the finish product is strangely sedate, unable or unwilling to snowball into a macabre take on mischief and murder. It’s restrained work from director Ben Browder, who strives to treat the screenplay carefully, respecting the source material, only to end up with a lethargic second round of suspense.
