Like an extremely strict aquarium, no one at the box office is going to be touching theGlassthis weekend. DirectorM. Night Shyamalan’s twisty comic book thriller took home $4.9 million in its second Friday night, looking to bring in another $15-16 million by the end of the weekend.The Upsideis also sticking around, having itself a solid little $3.1 million Friday night, on track for a $10-12 million showing in its third weekend. But the newcomers are off to an un-kingly start, to say the least. Arthurian updateThe Kid Who Would Be King’s sword is still firmly stuck in the stone from the start, opening to a disappointing $1.7 million on Friday—the same take asAquamanin itstenthFriday—and trending toward $8-10 million. The twisty noirSerenitystarringMatthew McConaugheyandAnne Hathawayfared even worse, sailing toward a $4-6 million debut.

The Kid Who Would Be Kingis directorJoe Cornish’s first film since 2011’s stellar alien invasion flickAttack the Block. For his latest, the English filmmaker took on the legend of King Arthur, withLouis Ashbourne Serkisplaying a grade-schooler who discovers the mythical sword Excalibur. Critics have been pretty kind to the film—our own Matt Golbergcalled it"thoughtful, funny, cute, and charming for both kids and adults"—and it landed a solid B+ CinemaScore, but the numbers are disappointing considering its Cornish’s comeback and the fact it came with a $60 million price tag.

Serenity, however, is landing with a thud both at the box office and with audiences, garnering a brutal D+ CinemaScore. Written and directed bySteven Knight, the seaside noir tale—which includes a plot twist that we willnotbe discussing here—stars McConaughey as a fishing boat captain whose ex-wife (Hathaway) asks to take part in a murder.
