The best new movies on streaming and Netflix this weekend (April 10-12)

This is a big week for genre mash-ups on streaming. Thrash combines a disaster story and shark movie as the survivors of Category 5 hurricane must avoid killer fish stalking the streets of their flooded town. The horror thriller swims onto Netflix. Sevenscreenwriter Andrew Kevin Walker and first-time director Gavin Polone blend serial killer thriller tropes and a slasher film’s ornate on-screen kills in the throwback film Psycho Killer, which carves a bloody path onto VOD.
