My kids loved binge-watching some TV in the last lockdown. And by that, I just mean getting their teeth into some tele on bad weather days in between schoolwork! Mostly...
They liked The Worst Witch (iPlayer), The Inbestigators (Netflix), Round the Twist (Amazon), Mallory Towers (iPlayer), A Series of Unfortunate Events (Netflix), Ghostwriter (Apple), The Mandalorian (Disney!), The Secret Life of Boys (iPlayer).
Kids are 10ds and 6dd and viewing as you can see is mostly at the 10yr old level (I know I know). They like reasonable quality, compelling tv (who doesn't). So what do they watch next? I can't bear listening to them argue about Minecraft yet again... I see there's a bunch of Tracy Beaker related stuff on iPlayer but I haven't heard anything good about it. I don't think they'd watch The Next Step and don't seem to be into vampire drama.
