It’s been a busy week in the world of geek TV, so we round it up here.

DC Universe has canceled its new Swamp Thing series after only one episode was released on the subscription streaming service (the remaining episodes will drop as scheduled), according to Deadline.  The news comes after production was shortened from 13 episodes to ten after shooting was underway (see “’Swamp Thing’ Teaser, Season Shortened”), and as questions have been raised about the future of DC Universe (see “As WarnerMedia Reconfigures Its OTT Strategy, What’s Ahead for DC Universe?”).

Swamp Thing wasn’t the only geek TV series to get cut short this week; Syfy has canceled Deadly Class and Happy, according to Variety.  Deadly Class, based on the Rick Remender and Wes Craig Image series, debuted in January.  Producers plan to shop the show, according to the report.

Happy, based on the Grant Morrison – Darick Robertson comics, ran two seasons, with screen legend Ann-Margret joining cast members Christopher Meloni, Patton Oswalt, and others for the season (see “Ann-Margret Gets ‘Happy’”). Producers will also shop Happy to other networks.

Meanwhile, Lucifer is extending its run, although the end is in sight; the upcoming fifth season will be its last, according to Variety.  The series, featuring a character created for comics by Neil Gaiman, Sam Kieth, and Mike Dringenbergk, ran for three seasons on Fox before being canceled.  Netflix picked up the show beginning with Season 4 (see “’Lucifer’ Finds Salvation”).

Two new animated series were announced this week.  Netflix will debut Jurassic World: Camp Cretaceous globally in 2020, the streamer announced this week.  Set in the 2015 film’s timeline, the action-adventure series will follow six teenagers stranded by the dinosaurs that are wreaking havoc on the island. 

Nickelodeon has greenlit Kamp Koral, a SpongeBob SquarePants spin-off in which SpongeBob is a 10-year-old at summer camp.  It will begin production this month.

And Netflix has released a full trailer for the third and final season of Jessica Jones, debuting June 14. Only a short teaser had been previously released (see “Teaser for ‘Jessica Jones’ S3”).
