Streaming in September was eclectic. The top 10 most popular TV shows of the month, according to data from JustWatch, include opposite takes on international espionage — Lioness’s “everything is at stake” blockbuster vibe versus Slow Horses’ darkly funny, morally ambiguous style.
Other series burning up the charts: spy-adjacent action show Reacher, a couple of sports comedies named after their main characters (Ted Lasso and Chad Powers), a dystopian sci-fi drama (Silo), a superhero show (Lanterns), and stories of criminals and cops (Furious and The Gentlemen). There’s even a horror comedy (Widow’s Bay). You could say there’s something for everyone.
Lanterns
Topping the streaming charts this month is DC’s TV revamp of Green Lantern, in which experienced Lantern Hal Jordan (Kyle Chandler) trains the new guy, John Stewart (Aaron Pierre), on how to wield the mysterious and powerful Green Lantern Ring. It’s a reserved, neo-noir style take on the comic mythos, as the heroes investigate a series of murders tied to an extraterrestrial threat. Lanterns is pulling in a 92% fresh rating from Rotten Tomatoes, so it’s definitely worth a stream.
Ted Lasso
Season four of Ted Lasso sees the title character, played by Jason Sudeikis, returning to the UK to take on a new challenge: coaching the Lady Greyhounds, AFC Richmond’s second-division women’s football team. This multiple Emmy Award-winning series still has all the heart, humor, and positivity of the original run.
Reacher
Reacher actor Alan Ritchson is a great action star. Dude’s the size of a house, but he uses his brains as much as his fists, and his “independent ass-kicker” lifestyle makes for great TV. Season four sees our morally uncompromising, giant-sized hero witnessing a supposed suicide, then finding out it’s tied to a conspiracy so huge that world governments are involved. If you like your TV action-packed, you’re probably already watching Reacher, but if you’re not, get on it.
Lioness
If you like action, international espionage, and incredible performances, Lioness mashes them all up into a must-watch series. This cast is without lightweights, including Oscar winner Zoe Saldaña, Oscar winner Morgan Freeman, Emmy nominee Michael Kelly, and executive producer and Oscar winner Nicole Kidman. Season 3 dives into a hidden network of dangerous foreign operatives, personal betrayals, and a high-stakes war that could define everyone’s lives.
Slow Horses
Apple TV+‘s Slow Horses delivers a more realistic, nuanced take on espionage by detailing the lives of the losers of British Intelligence. Instead of chiseled good guys and gals saving the world, the agents of Slough House are a team of dysfunctional, troubled souls trying to do the right thing (usually) in a morally gray world. Their leader, gruff and obnoxious Jackson Lamb, is played to perfection by Gary Oldman. Slow Horses has an almost perfect Rotten Tomatoes score over its first five seasons, and season 6 is setting new records.
