TV THIS WEEK: Roswell returns; The Atom exits Legends; Altered Carbon: Resleeved; and more

There's plenty of cool genre stuff to check out this week, including two major premieres and a brand new cyberpunk streaming series on Netflix.

The big stories this week are the Season 2 premiere of The CW's alien drama Roswell, New Mexico; the series premiere of HBO's The Plot Against America; and the series drop of cyberpunk continuation Altered Carbon: Resleeved on Netflix. Digging a bit deeper, most of the Arrowverse is new this week — though the highlight of that lineup is Legends of Tomorrow, which will bid farewell to longtime series regular Brandon Routh. The Flash is also looking good, as Barry once again faces off with his old nemesis, Reverse-Flash.

Beyond that, HBO has a new episode of Westworld (plus the network premiere of Dark Phoenix, in case you're wanting to revisit the final proper X-Men movie of the Fox era), Supernatural is back on The CW, The Magicians is new on SYFY, and NBC has a new episode of its mystery drama Manifest, Fox has a new LEGO Masters, and Apple TV+ is dropping a fresh installment in its genre anthology Amazing Stories. Plus a whole lot more.

Check out our full rundown below and let us know what you'll be watching, bingeing, and generally geeking out on.
