It's the end of the season as we know, and most of your favorite shows are either ending for the year — or wrapping up for good. From the Arrowverse to Riverdale, here's what you should be checking out this week.

Fox tragically pulled the plug on the loose DC Comics adaptation Lucifer just a few days ago, and the season finale this week will serve as the de facto series finale. The show was a ton of fun, and the finale looks to at least bid farewell in style. The network is also wrapping the latest season of Gotham, though that series has been renewed for a final season in the fall.

The CW is wrapping the brunt of its primetime schedule, with Arrow, Supernatural, Riverdale all dropping season finales (thankfully, those have all been renewed). Marvel's Agents of S.H.I.E.L.D. is also ending its fifth season with an episode titled, ahem, "The End." No word yet on a renewal for Season 6, though the series is apparently still in contention. It's also been creatively fantastic the past few seasons, for whatever that's worth.

SYFY doesn't have anything in the way of finales, though there are new episodes of both Krypton and The Expanse. So, head to deep space, then back in time to the DC universe.

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