TV THIS WEEK: Felicity's Arrow origin, Doctor Who's finale, and more!

It is another busy week of TV, headlined by a climactic Doctor Who episode.

It seems like only yesterday we were meeting Peter Capaldi's Doctor for the first time, and now it's time to say goodbye ... until December, anyway. The season finale of Doctor Who hits Saturday, and the show might never be the same. Plus Felicity's origin story on Arrow, Papa Midnite arrives on Constantine, a 75th-anniversary Marvel special, and much more.

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

Highlights of the Week

Marvel 75 Years: From Pulp to Pop (ABC) Tuesday, 9 p.m.

One-hour special! - Agents of S.H.I.E.L.D. is off this week, and in its place Marvel is airing a one-hour special to celebrate the company's 75th anniversary. Hosted by Captain America: The Winter Soldier co-star Emily VanCamp, the special will trace Marvel's entire history from 1939 to the present, including its beginnings as Timely Comics, its creative boom in the 1960s under creators like Jack Kirby, Stan Lee and Steve Ditko, its struggles with bankruptcy in the 1990s, and its rise to pop-culture powerhouse in the age of the superhero movie universe. If you're a Marvel fan already, this might feel like a company victory lap that won't tell you anything you don't already know, but ABC has promised some sneak peeks at Marvel's future, so you just might get a glimpse of something you haven't seen before. Check out a preview below.

Arrow (CW) Wednesday, 8 p.m. - "The Secret Origin of Felicity Smoak" 

Arrow's now got four episodes under its third-season belt, and the fifth promises something special for fans. Before we get to that, though, let's have a look at how the show's doing in ratings so far this year. The season-two premiere last fall was a strong but ultimately disappointing showing, pulling in fewer viewers than both the series premiere (by far) and the season-one finale (by a little). Season three's premiere, though, managed to top season two's debut by about 100,000 viewers, with a Live+Same Day total of 2.83 million, and while episode two slumped a little with 2.32, the last two episodes have hovered at right around the 2.5 million mark. That's about on par with Arrow's overall season-two performance, and of course DVR viewers will add a little boost to that. Bottom line: If you're an Arrow fan, you don't really need to worry about the show going anywhere for the moment. Instead, look forward to some special season-three episodes that will quite possibly provide a boost in viewers, like the looming crossover with fellow hit The Flash and this week's show, which will finally give us insight into Felicity's past. Check out a preview below.

The Almighty Johnsons (Syfy) Wednesday, 11 p.m. - "And Then She Will Come To You"

Season premiere! - Syfy's had a lot of success with imported genre series like Lost Girl and Continuum, which both came from Canada. Earlier this year, the network added this New Zealand-based fantasy series about a family of reincarnated gods. The show carved out a comfortable little U.S. audience for itself over the summer, airing late Friday nights, and now it's moving to mid-week, where it could get even more attention. Oh, and take note: Episode two will follow the very next day, on Thursday night. In the season-two premiere, Axl's on the hunt for Frigg, but all of his brothers seem too preoccupied to help him. Check out a preview below.

Constantine (NBC) Friday, 10 p.m. - "The Devil's Vinyl" 

There are big DC Comics happenings on Constantine this week, so we thought we'd use this opportunity to both talk about that particular higlight and discuss how the show's ratings fared over the first two episodes. First, the good news. Despite premiering on a Friday night opposite a World Series game, Constantine's debut was a solid one, with 4.3 million viewers and a demo score of 1.4, down just a tenth of a point from the demo score of its lead-in, Grimm. Now, to be fair, NBC's Dracula premiered a good bit stronger than that in the spring, only to slip away and get canceled, but it's worth remembering that Dracula wasn't premiering against the World Series. Now the bad news. Halloween night was rough on the show, dropping it to 3.1 million viewers and an 0.9 demo score. We are talking about a major holiday that just happened to fall on a Friday night this year, though, so we can chalk a lot of that drop up to people just not watching as much TV in general that night. Or at least, we can for now. The coming weeks will be a big test for the show as it tries to find its feet in a tough timeslot. It could easily bounce back from that Halloween slump and end up thriving on Friday nights just like network-mate Grimm has, but viewers are going to have to be compelled to stick around. This week's episode could go a long way toward making that happen, as the show expands its DC Comics roster with the introduction of a long-serving Constantine villain and sometimes reluctant ally Papa Midnite. Check out a preview below.

Doctor Who (BBC America) Saturday, 9 p.m. - "Death In Heaven"

Season finale! - This week, we come to the end of the first season of the Peter Capaldi era, and we bid farwell to the Doctor until it's time for his Christmas special. Capaldi's time in the TARDIS, under the guidance of showrunner Steven Moffat, has proven rather divisive among Who fans, but it's also proven rather provocative, and the penultimate episode of the season left us hanging with a big twist that has major implications for the final super-sized (90 minutes of U.S. airtime) broadcast of the season. On the ratings side of things, Capaldi started quite strong, delivering the best U.K. Who premiere since Matt Smith's first outing back in 2010 and giving BBC America its highest-rated premiere ever. The numbers have slipped a bit since then, but with a November finale that promises big developments and a Christmas special looming, Capaldi's Doctor has a shot at more big ratings booms. As for where the story will take the characters next, there's been speculation since before the season even began that the Doctor might be alone in the TARDIS again by the end of 2014. As for whether that happens, and what might follow it, well ... we just have to watch and find out. This week the Doctor must take on a new role, Cybermen invade London and UNIT works to contain Missy. Check out a preview below.
