Making the grade
Just because Gillian Anderson is sporting a British accent, don’t mistake “Sex Education” for a crusty, sophisticated comedy. The former “X-Files” investigator plays a sex therapist whose teenage son (Asa Butterfield) decides to follow in Mom’s footsteps, taking on his schoolmates as clients. It’s a clumsy, uncomfortable mess — just like young love. Emma Mackey, who plays Butterfield’s “business” partner, is the best thing to happen for teenage sarcasm since “Veronica Mars” was in session.

Does not compute
If the hybrid approach to storytelling in “Mars” didn’t leave you lost in space, you may enjoy “Valley of the Boom,” a docudrama on the rise of Silicon Valley that breaks the fourth wall while employing puppets, rap music, interviews with Arianna Huffington and an unhinged Steve Zahn in a fat suit. The rise of the internet is fascinating enough without filmmakers overloading the system.

Back on the beat
If “Moonlight” and “Green Book” didn’t convince you that Mahershala Ali is one of our most intriguing and subtle actors, the new season of “True Detective” should do the trick. Try to forget the disastrous second season (except for Rachel McAdams’ performance) and settle in for a patiently paced, moody tale with Ali nailing his part as a retired investigator wrestling with regret. As it did during the first season’s Matthew McConaughey-Woody Harrelson arc, this feels more like a ghost story than a crime procedural.

All hail the Queen
Fans of “Downton Abbey” and “The Crown” should be downright giddy about the third season of “Victoria,” which dives deeper into the relationship between Jenna Coleman’s Queen and Tom Hughes’ Albert. The premiere is followed by “Victoria and Albert: The Wedding,” a new series that re-creates the royal couple’s nuptials.
