It's another big week for finales, including the final episode of a beloved Syfy original series.

We're in a strange in-between period of television right now, when many of the fall shows have already wrapped up and many of the summer shows have not yet premiered, but that doesn't mean we don't have plenty to talk about. This week, Warehouse 13 says goodbye after five seasons, Supernatural ends its ninth season with a 10th on the way, Revolution ends its two-season run, and Believe begins its final block of episodes before cancellation. Plus Penny DreadfulSalemThe 100 and more. 

Check out the week in genre TV below. What's on your watchlist?

Highlights of the Week

Warehouse 13 (Syfy) Monday, 9 p.m. - "Endless"

Series finale! - Well, after five seasons, more than 60 episodes and a whole lot of artifacts, one of Syfy’s biggest original series ever is coming to an end. Warehouse 13’s blend of fun procedural antics and serious genre fuel earned it a loyal fan following right from the start, and now we’ll be faced with a void in our lives on Monday nights that the network will seek to fill with a number of other original programs in development. That doesn’t mean we’ll ever stop missing the Warehouse and its team, though, so let’s give it a strong sendoff while we can. In the final episode, the team faces the transfer of the Warehouse to a new country, relives what made them all come together, and creates a time capsule. You should probably have a tissue ready for that, but that doesn’t mean there won’t be some fun, too. Check out the latest problem in the Warehouse in this sneak peek.

Supernatural (The CW) Tuesday, 9 p.m. - "Do You Believe in Miracles"

Supernatural continues to be a powerful example of TV endurance in an age when quite a few genre series are still canceled after a single season. Now that Smallville’s gone, it’s The CW’s senior series, and its devoted fanbase shows no signs of wanting to let it go. This is a show that’s so embedded in certain pop-culture circles that, even after a planned spinoff didn’t get picked up by The CW for next season, news came out that another spinoff might already be in development. For the moment, it seems there’s no stopping Supernatural while the principals involved want to keep telling stories, so if you’re looking forward to another year of Winchester adventures, celebrate your victory with the season finale, in which Metatron makes his move against humanity and Sam, Dean and Castiel fight to stop him. Check out a clip below.

Revolution (NBC) Wednesday, 8 p.m. - "Declaration of Independence"

Series finale! - Revolution began with an intriguing post-apocalyptic hook -- a world without electricity -- and quickly evolved into a story all its own, an adventure marked by warlords, secrets and a reshaped vision of America. Unfortunately, its early audience didn’t stick around for the direction the show ended up heading in, and its future has been in doubt for some time. Now we know the season-two finale will be the last episode of the series. Revolution’s cancellation marks not just a loss to genre programming on NBC (which will also lose Believe later this year), but a loss to J.J. Abrams' Bad Robot production company, whose once-unrelenting slate of TV projects is now dwindling. There’s plenty of room for both NBC and Bad Robot to rebound in the genre TV department, though. So, for now, let’s focus on saying goodbye to Revolution, in an episode that sees Miles and Charlie fighting to prevent a war between California and Texas, and Neville out for revenge. Check out a preview below.

Penny Dreadful (Showtime) Sunday, 10 p.m. - "Resurrection"

Penny Dreadful got off to a strong start with its series premiere two weeks ago, racking up solid viewership numbers that didn’t even count the hundreds of thousands of viewers who caught the pilot in advance. The series’ second episode also got a solid critical response, but its future still hasn’t been decided. Before the show premiered, before even fellow Sunday night series Salem premiered, I wondered just how many horror series television can handle at one time, particularly in a summer that’s also set to see the premiere of Guillermo del Toro’s The Strain in July. For the moment, Penny Dreadful looks to be holding its own. We’ll see if it can stay strong. This week, Vanessa has a vision of Mina, while Dr. Frankenstein must confront his past. Check out a preview below.

Salem (WGN America) Sunday, 10 p.m. - "The Red Rose and the Briar"

Though it hasn’t gotten the same critical buzz as Penny Dreadful, Salem seems to have slipped right into Sunday night cable and carved out a place for itself. I wondered how the show would fare not just because it was yet another supernatural horror series, but because it was heading out into a crowded Sunday night lineup that’s been dominated over the last few weeks by Game of Thrones. As it turns out, there wasn’t a need to worry. Salem did well enough in its initial episode to earn a second season renewal from WGN America. So if you like this witchy series, get set for more. This week, Mary finds a solution to the coven’s problems, and Cotton and Alden face a real witch.
