mysteryScienceFridays are big days for new shows online. Today’s include a couple that have been rescued from other formats.

Jonah Ray is the new host of “Mystery Science Theater 3000: The Return” (Netflix, streaming), which extends the conceit of a lonely space traveler accompanied by the same two robots, endlessly commenting on bad B-movies. The caliber of guest stars this time out seems improved with Jerry Seinfeld, Mark Hammill, Neil Patrick Harris and Joel McHale dropping by; and Patton Oswalt and Felicia Day recurring as villains. It’s also important which movie about which they crack wise. The first one is is a Danish monster movie. But gosh, what a lode: Fourteen episodes, each one about the length of the movie — 90 minutes — are all available at once.

I never expected to see “Fortitude” (Amazon, streaming) again. It was hard enough to find when the creepy frozen mystery had its first life on the now defunct Pivot cable channel two years ago. For season two, there are more mysterious crimes near the Arctic Circle and an American addition to the international cast in Dennis Quaid, about a fisherman seeking to cure his terminally ill wife played by Michelle Fairley.

Chelsea Handler is back for a second season of her very loose talk show “Chelsea” (Netflix, streaming), which has been retooled to be weekly hour long programs each Friday. Because that’s the big day for streaming services. Her first episode back includes a trip to India, and visits with Van Jones and the cast of “Nobodies,” including its producers and sometimes featured actors, Melissa McCarthy and Ben Falcone.

Maya Rivera and Jeffrey Bowyer-Chapman are guest judges on “RuPaul’s Drag Race” (VH1, 9 p.m.) which has just been renewed for another season on its new network.

Soprano Diana Damrau and tenor Vittorio Grigolo perform in Charles Gounod’s opera “Romeo et Juliette” on “Great Performances” (PBS, 9 p.m., check local listings). Gianandrea Noseda conducts.

Shelly Chartier talks about the time she catfishes NBA star Chris Andersen — from jail — on a new “20/20” (ABC, 10 p.m.).

Two episodes of “Dateline” (NBC, 9 p.m.) investigate two dead women.

“MacGyver” (CBS, 8 p.m.) reaches its first season finale.

A new kind of piñata is introduced on “The Toy Box” (ABC, 8 p.m.).

“You the Jury” (Fox, 9 p.m.) decides a case of online racism.

“Blue Bloods” (CBS, 10 p.m.) wonders if a teenager’s suicide was really a homicide.

Contestants on “The Pop Game” (Lifetime, 10 p.m.) are forced to meet Perez Hilton.

Dancers compete for a Broadway opportunity on “Bring It!” (Lifetime, 9 p.m.).

A guy on “First Dates” (NBC, 8 p.m.) has a few drinks before his encounter.

On “Gold Rush” (Discovery, 8 p.m.), it’s getting cold on the Klondike Trail and someone falls into freezing water in a second episode at 9.

A small town mayor has been murdered on “Rosewood” (Fox, 8 p.m.).

One of the last survivors of the USS Arizona is murdered on “Hawaii Five-0” (CBS, 9 p.m.).

A malevolent haunting occurs on “The Originals” (The CW, 8 p.m.).

The Stanley Cup playoffs move to the second games of the first round: Rangers at Montreal (USA, 7 p.m.), Columbus at Pittsburgh (NHL, 7 p.m.), St. Louis at Minnesota (NBC Sports, 8 p.m.) and San Jose at Edmonton (NBC 10:30 p.m.).

Baseball includes Pittsburgh at Cubs (MLB, 2 p.m.) and St. Louis at Yankees (MLB, 7 p.m.).

College baseball includes Oklahoma State at Kansas (Fox Sports 1, 8 p.m.); softball has Savannah State at Florida A&M (ESPNU, 3:30 p.m.) and Texas A&M at Arkansas (ESPNU, 6 p.m.).

It’s the women’s college gymnastics NCAA semifinals (ESPN2, 1 p.m.; ESPNU, 8 p.m.) with the individual all-around at 9 p.m.
