TV THIS WEEK: SYFY WIRE's The Great Debate, NOS4A2; HBO's hard-boiled Perry Mason

This summer week brings a heat wave of new premieres — ranging from freaky horror to hard-boiled action and a hit celeb panel geek-fest pioneered on the comic con circuit.

SYFY WIRE's own The Great Debate, a celeb-filled series with lots of nostalgia, jokes, and (you guessed it) geeky debate, comes to prime time. The Great Debate has been a hit at comic cons over the past few years, digging deep into hot topics related to everything from Star Wars to video games. HBO also has a high-profile series premiere with the genre-adjacent detective reboot Perry Mason. The hard-boiled miniseries stars The Americans alum Matthew Rhys and Orphan Black's Tatiana Maslany. Last but not least, AMC's NOS4A2 is back to scare us all to death for the summer.

Digging deeper, The CW has a new episode of DC super-series Stargirl (which is aiming to introduce a new Hourman and Dr. Mid-Nite this week); alien soap Roswell, New Mexico; and sci-fi thriller The 100. ABC has a new Marvel's Agents of S.H.I.E.L.D., which might just be changing the history of the MCU this week. TNT has a new Snowpiercer, Fox has a new Ultimate Tag (which is the silliest thing you can watch this summer in all the fun ways), and Showtime has a new Penny Dreadful: City of Angels.

On streaming, Netflix has a new season of the supernatural drama The Order, while DC Universe is dropping a new installment of its excellent Harley Quinn animated series.
