TV THIS WEEK: The Flash season finale; SurrealEstate on SYFY; He-Man returns; Trollhunters & more

The big story this week is the 2020 Tokyo Olympics, which commence on NBC this weekend with a boatload of major events. But don't worry, there's still a smattering of sci-fi premieres, finales and specials this week to keep us busy.

SYFY has a new episode of its latest original scripted series SurrealEstate, which follows a real estate crew that takes on the haunted houses hitting the market. This week's episode focuses in on a little boy's "imaginary friend" who is making it a bit hard to sell his childhood home. The CW has the season finale of The Flash, which is wrapping up an admittedly uneven and shortened pandemic-era season with a finale focused on the present and future of the Flash family. The network also has a new Superman & Lois on tap. 

Streaming is loaded this week with interesting projects, including the premiere of the He-Man revival series Masters of the Universe: Revelation on Netflix; plus the franchise-ending Trollhunters film Rise of the Titans. Disney+ has the latest Assembled episode, which goes behind the scenes into the making-of its latest original series Loki. The Mouse House streamer also has the premiere of its new Turner & Hooch original series.

Digging deeper, there's a new LEGO Masters at Fox; the Charmed season finale on The CW: a new Star Wars: The Bad Batch at Disney+; and (of course) continued 2020 Tokyo Olympics coverage.

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