TV THIS WEEK: Crisis on Infinite Earths comes to an end, The Magicians returns, and more

It's been a long holiday break, with every universe in the DC multiverse destroyed and all, but now we finally get the big finale for The CW's Crisis on Infinite Earths event.

The epic finale to the Arrowverse's latest and biggest event hits with a two-parter this week. We're still anxious to find out just how many universes will survive once this thing finally comes to an end. Or will everything just be reset (except for Oliver Queen's demise, of course)? So many questions; here's hoping it's packed with answers.

SYFY's The Magicians also returns for a new season, after an acclaimed and controversial 2019 that saw series lead Quentin Coldwater (played by Jason Ralph) sacrifice himself for his friends. The series enters a new era for Season 5, moving on in the wake of Quentin's departure. NBC also has a new episode of The Good Place, as it glides toward a rewritten take on the afterlife, plus a new installment of Manifest.

There's also a new Nancy Drew, Charmed, Emergence, The Outsider and a whole lot more. Check out the full rundown below and let us know what you'll be watching this week.
