TV THIS WEEK: Stargate and Smallville sign off forever, and more!

It's a big week for Stargate and Smallville fans as Stargate Universe and The CW's Superman prequel end their runs. After 14 years of Stargate and 10 years of Smallville, television is not going to be the same without them. This week, we'll also get season finales for The Vampire Diaries and Nikita.

Also, Chuck and Sarah have a rescue mission to take care of before their wedding on Chuck, Sophia puts her plan for wiping out the humans into action on The Event, Will and Henry's double date gets complicated on Sanctuary, Howard tells his mother he's getting married on The Big Bang Theory, Damon finds that dying isn't easy on The Vampire Diaries, Alex goes rogue on Nikita, Morgan's castle gets attacked on Camelot, the Doctor believes there may be another Time Lord alive but in trouble on Doctor Who, Rob Estes stars in a Hallmark movie called Edge of the Garden, The Cleveland Show heads to Comic-Con and the King issues orders Ned struggles with on Game of Thrones.

Here's what we have to look forward to this week on sci-fi, fantasy, paranormal and spy-fi TV, and non-sci-fi shows that have sci-fi content or guest stars.

Stargate Universe (Syfy) 9 p.m. - "Gauntlet"

Series finale! After nearly 14 years of Stargate on television, the Stargate will finally close with Stargate Universe. While the Drone storyline hasn't been as intriguing as the crew learning they had descendants via other versions of themselves, and I've missed the complex battles between Col. Young and Rush as they've started to work together to survive, it is undoubtedly the end of an era. In the final episode, the crew discover they are in deeper trouble than they thought when they learn the Drones are waiting for them at every planet with a Stargate. How do you think the series should end?

Here's a preview and a sneak peek:

Sanctuary (Syfy) 10 p.m. - "Wingmen"

Will and Henry's plans for a double date get interrupted when Magnus asks them to make a delivery involving an Abnormal, and the creature escapes.

Season-two finale! It's another huge finale for Diaries as Elena and gang discover the consequences of Klaus' deeds. And as Damon suffers from the results of the werewolf bite, a town-square showing of Gone With the Wind leads to memories of Katherine in 1864.

Smallville (The CW) 8 p.m. - "Finale"

Two-hour series finale! Lex alert! Michael Rosenbaum returns as Lex (finally!) for the finale. While there's not much info about the episode's story, according to the press release: "The story of Clark Kent (Tom Welling) culminates in this epic two-hour series finale as Clark takes the last step to becoming the Man of Steel. With surprise guest appearances, nods to the first few seasons of the series and Michael Rosenbaum's return as Lex Luthor, this final episode wraps up a decade-long story following one man's journey to becoming the world's greatest superhero." With John Glover, Annette O'Toole and John Schneider on board, it almost seems like old times.
