#’The Suicide Squad’ trailer looks shockingly decent

The first trailer for “The Suicide Squad” dropped Friday, and the upcoming DC Extended Universe film looks nothing like its horrendous predecessor.

That 2016 movie — starring Margot Robbie, Will Smith, Jared Leto, Viola Davis and David Harbour — hauled in $746.8 million at the global box office, but critics hated it.

Director David Ayer’s film currently holds a 26 percent on RottenTomatoes, and in his review, The Post’s critic Kyle Smith said, “What promised to be a Super Bowl of villainy turned out more like toddler playtime.”

Now, director James Gunn of Marvel’s popular “Guardians of the Galaxy” movies has rebooted the DC series — no, it’s not a sequel — by injecting his signature humor and only keeping around Robbie’s Harley Quinn, Davis’ Amanda Waller and Jai Courtney’s Captain Boomerang. Most of the villains are new to the Squad, and Will Smith, who left due to conflicting scheduling, is notably absent.

This time, we meet Bloodsport (Idris Elba) and Peacemaker (John Cena), Blackguard (Pete Davidson), Thinker (Peter Capaldi) and King Shark (voiced by Sylvester Stallone), among other new cast members.

Warner Bros.’s jungle-set reboot — expected to be rated R — also appears much more colorful than the murky 2016 flick, which is a stark contrast to Zack Snyder’s recent sooty “Justice League” recut.

“The Suicide Squad” hits theaters and HBO Max on Aug. 6.
