TV THIS WEEK: Legends of Tomorrow finale; S.H.I.E.L.D.; Bruce Lee's 30 for 30; Ad Astra

We're reaching the doldrums of the summer schedule, which has only been exacerbated by the pandemic that has shut down production of pretty much everything across the globe. But even a bit thin, there's still plenty of cool genre and genre-adjacent programming on the dial.

The big story this week is the season finale of the wackiest superhero show out there, DC's Legends of Tomorrow. Reality has been rewritten, and these B-list heroes are on the case to set things right. The network also has a new episode of Stargirl, a new The 100, and a new Roswell, New Mexico. If you're looking to make yours Marvel, ABC has a new episode of Agents of S.H.I.E.L.D.'s final season, which is still zipping through time. Want high-concept sci-fi? TNT is answering the call with a new Snowpiercer.

Digging deeper, FX has a new What We Do in the Shadows, NBC has a new Blindspot, DC Universe has a new Harley Quinn, and Showtime has a new Penny Dreadful: City of Angels. Getting a bit more genre-adjacent, ESPN has a new 30 for 30 documentary on the career and legacy of action legend Bruce Lee, and Fox has a new episode of the wildly silly (and stupid fun) Ultimate Tag. Of course, Netflix's recent drop Space Force is also live, if you're just looking for a binge.

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