TV THIS WEEK: Stargirl and The 100 premieres; Celebrity Escape Room; Ready or Not on HBO

The summer is always a weird time for TV, and with a global pandemic underway, it's only getting weirder. So this week is a mix of midseason sci-fi shows, some outside-the-box reality TV fare, and a great movie or two. Let's dig in.

The CW is definitely leading the charge this week when it comes to premieres, dropping the new superhero series Stargirl and the new season of long-running sci-fi saga The 100. Of course, Stargirl is also a DC Universe original (The CW is also set to air fellow DC Universe series Swamp Thing this fall), but it should fit in nicely with the network's lineup.

As for the reality TV stuff, it's a grab bag of genre-adjacent ideas that could actually be kinda fun while we all kick back on the couch to keep on flattening the curve. NBC has Celebrity Escape Room, with Jack Black hosting a who's who of celebs as they try to bust out of a puzzle room. Fox has something with a bit more American Gladiators-style flair in Ultimate Tag, which is basically what it sounds like — an anything-goes game of tag. Which sounds just goofy enough to actually be entertaining.

Digging a bit deeper, there's plenty of other stuff on the docket: HBO has the network premiere of the fantastic thriller Ready or Not; The CW has new episodes of Roswell, New Mexico and DC's Legends of Tomorrow (which is putting its own spin on the zombie apocalypse this week); FX has a new What We Do in the Shadows; DC Universe has a new Harley Quinn; Amazon Prime is dropping the new season of Homecoming; plus a whole lot more.

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