TV THIS WEEK: What We Do in the Shadows S2; LEGO Masters finale; 'One World' live

One of the funniest shows out there returns for its second season while the surprise hit LEGO Masters finally reveals who's the best builder of them all — plus a whole lot more on TV this week.

The vampire sitcom What We Do in the Shadows makes its blood-sucking return for more laughs on FX and LEGO Masters wraps up its run with what will hopefully be some of the coolest builds yet. HBO also has a new episode of Westworld, which has been dropping bombshells left and right this year; SYFY has a new Vagrant Queen, and The CW has some fresh originals like Charmed and Riverdale cued up. On streaming, DC Universe has a new Harley Quinn, Disney+ has a new Star Wars: The Clone Wars, and Netflix is dropping fresh episodes of the animated series The Last Kids on Earth.

If you're looking for something outside the box, the multi-network live event One World: Together at Home will be airing on NBC, CBS and ABC, co-hosted by late night hosts from each network (Jimmy Kimmel, Stephen Colbert and Jimmy Fallon). Sure, it's not exactly genre, but it could make for something unique and communal while we all self-isolate. Saturday Night Live is also expected to be back again with the comedy stars filming segments from home (though that's obviously a bit subject to change).

Check out our full rundown below and let us know what you'll be watching.
