I've enjoyed it though the ending was a disappointment: was like it stopped one episode too soon.
Octo-eye going on a zombie-esque saunter across Earth raises intriguing possibilities (mostly scary, as it doesn't have character as yet).
Where do the 'kids' go from here? To be taken by the WY assault team? To escape the island and go on their own wanders and adventures around the universes? Maybe the writers don't yet know?! Ending the series as it did, without even a hint of future direction, just chitty-chatty with a bunch of prisoners, was a bit meh.
But I expect I'll watch series 2, I'm just a bit disappointed that it could have been on a par with say Andor/Rogue one but wasn't.
