Well, it's a bit of a shame but actually, they'd pretty much wrapped up the story satisfactorily in one season. They did allow for continuation with the way they left things but it still works as a one-shot season.

Pleased about this. It's a bit of an odd show and the acting is all over the shop, but it's watchable, explores some interesting ideas and a scifi show that isn't part of a gargantuan franchise is as rare as hen's teeth and should be encouraged.

Interesting choice of day for Deadline to publish this story. Probably just a coincidence. https://en.wikipedia.org/wiki/International_Transgender_Day_of_Visibility

To be honest, It's a small miracle that something as weird and wonderful as Doom Patrol actually got 4 seasons. And a properly foreseen and planned series finale is the cherry on top.
