Feel the love for TV this Valentine’s Day, regardless of your type:
“Helix” (Friday, 10 p.m., Syfy)
A “Star Trek” alum can make any geek’s heart flutter, so this Billy Campbell vehicle delivers a mean but sexy Jeri Ryan (Seven of Nine, “Star Trek: Voyager”) playing the CEO of the evil corporation that created the Arctic virus the gang is fighting. No telling what Dr. Hatake (Hiroyuki Sanada) will do now that his boss is on the base.
“Arrow” (Thursday, 9 p.m., The CW)
Sure, it’s a rerun, but if you missed him — because he’s so quick; get it? — you can catch the introduction of The Flash, whom Oliver (Stephen Amell) and his abs met earlier this season. Grant Gustin’s Barry Allen only appeared in two episodes, but he provided enough of an upbeat contrast to this normally dark comic-book drama that we look forward to him suiting up for his own series shortly.
“Rake” (Thursday, 9 p.m., Fox)
If your tastes in men run toward the creepy, has Mama got the guy for you. Denis O’Hare, last seen replacing his bizarre doll collection with real babies on “American Horror Story: Coven” is playing another sicko as an accused cannibal whom Keegan (Greg Kinnear) must defend.
“Good Luck Charlie” (Sunday, 8 p.m., Disney)
Now that big sister Teddy (Bridgit Mendler) is heading off to college and baby Charlie is no longer as cute and cuddly — her portrayer, Mia Talerico, is 5 years old — the Duncan family is bidding adieu in this final episode after four seasons of making their parents look like dopes.
“The Good Mistress” (Saturday, 8 p.m., Lifetime)
Like the Euro trash bad-boy type? Italian hottie Antonio Cupo plays the political husband who cheats on his wife in this obvious title-knockoff of the “The Good Wife.” Annie Heise plays the recovering alcoholic hussy who unknowingly sleeps with her pal’s hubby, after which she discovers that he may also have killed someone.
“Downton Abbey” (Sunday, 9 p.m., PBS)
For the old-fashioned romantic, go with the widow Mary (Michelle Dockery) as she chooses between sniffing suitors Lord Gillingham (Tom Cullen) and Charles Blake (Julian Ovenden) in the penultimate episode of the costume drama. One of them has more money than you would think.
