Lea Michele stars in “Glee”

Tears of 'Glee': All good things must come to an end, as they say, and that includes TV shows. After six music-filled seasons, Fox's "Glee" is wrapping up for good with its series finale Friday, March 20.

When it first hit the small screen in 2009, "Glee" was an almost immediate hit. Musicals don't often pop up on TV, and this breath of fresh air reeled in the audiences. Emmy nominations and victories followed soon after, and while both accolades and audience numbers have slipped in recent seasons, "Glee" still maintains a loyal and devoted fanbase.

It has been confirmed that at least one of the show's previous actors will be returning for the final episode. Jonathan Groff ("Frozen," 2014), who played rival glee club member Jesse St. James through the show's first three seasons, will be making an appearance during the final send-off. Whether any other former members of the show's cast will also be on screen to say farewell remains to be seen.

Sadly, no mention of "Glee's" end can be made without remembering Cory Monteith ("Final Destination 3," 2006). The young Canadian actor died in July 2013 after a tragic history of substance abuse. The outpouring of sympathy for the young life cut short was overwhelming, and "Glee" co-creator Ryan Murphy announced soon after that the sixth season would be the show's last.

The end of any beloved show is a sad event, but with the specter of Monteith's passing still fresh, "Glee's" end may be even more tear-jerking than some. For a show that's always embraced dealing with difficult or controversial issues, though, it's a safe bet that it won't shy away from this one either.

"Glee" watchers won't want to miss the final farewell when it airs Friday, March 20, on Fox.

Undead fever: It's a show based on a popular series of comic books about zombies with a hunger for human brains taking over. No, it isn't AMC's "The Walking Dead." It's the CW's new take on the zombie genre, "iZombie."

A "Walking Dead" clone this is not. Premiering Tuesday, March 17, "iZombie" has been compared to two other beloved shows: "Veronica Mars" and "Buffy the Vampire Slayer."

Unlike "The Walking Dead" -- a show that "iZombie" will no doubt be constantly compared to -- this undead serial is a bit more lighthearted. Rose McIver ("Once Upon a Time") stars as Liv, a promising medical student who ends up in the middle of a zombie feeding frenzy.

Now one of the living dead herself, she struggles with a hunger for humans -- and finds that she can absorb memories from those that she consumes. Naturally, she turns to solving crimes and tracking down bad guys.

It sounds just ridiculous enough to work, and a strong cast of actors has lined up to get their zombies on. Malcolm Goodwin ("Breakout Kings") stars as a detective who's in on Liv's secret and enlists her to help him solve crimes. Robert Buckley ("One Tree Hill") is on board as a major character from Liv's past, and Rahul Kohli ("I'll Be Home Soon," 2014) stars as her boss at the coroner's office.

Other actors rounding out the cast include David Anders ("Alias"), Aly Michalka ("Hellcats") and Molly Hagan ("Unfabulous").

TV royalty: Love them or hate them, there's no denying that the British Royal Family is in the news an awful lot. Their every move is scrutinized and reported on, and huge numbers of people, even on this side of the Atlantic, eat up every piercing little word written about them.

E! has built its reputation on reporting on celebrity, and for its first-ever scripted series, it's not straying too far from its roots.

"The Royals" premieres Sunday, March 15, on E!, but don't worry: the House of Windsor hasn't signed on to a scripted TV series. This show is all fiction, with a fictional British royal family dealing with a lot of the same issues that all big families go through -- but with the paparazzi a constant presence.

Headlining the cast is Elizabeth Hurley ("Gossip Girl") as Queen Helena, the queen consort to King Simon (Vincent Regan, "300," 2006).

"It's a very nice combination of what the public sees and what the public will never see," said Hurley in summing up just what the show is all about.

Also filling out the family are William Moseley ("The Chronicles of Narnia: The Lion, the Witch and the Wardrobe," 2005), Alexandra Park ("Home and Away") and Oliver Milburn ("The Descent," 2005).

"The Royals," E!'s first-ever scripted series, premieres Sunday, March 15.
