The top three Paramount+ shows worth watching this weekend, September 18–20, 2026, are all major franchises with brand new episodes streaming now. Between a historically celebrated animated series, a mesmerizing and intense spy action thriller, and the return of one of the best crime gangster series on any streaming platform, these three Paramount+ shows are all acclaimed must-watch hits. Apart from these Paramount+ streaming recommendations, ScreenRant also has binge-watching guides for Netflix, Prime Video, HBO Max, Apple TV, and Disney+, which can all be accessed here. For Paramount+ specifically, there's truly no better new shows to watch this weekend than the following three, although other recent releases such as Golden Axe and Route 187 are worth mentioning as well. South Park South Park has officially returned with its 29th season premiere, which just landed on Paramount+ on Thursday, September 17. The monumental animated comedy series has leaned heavily into its South America title change this season, with the entire first episode titled "South America Biker Gangs" poking fun at it. While only the first of six South Park season 29 episodes are available to stream right now, the entire series offers more than 330 episodes and is always a safe bet for viewers looking for unfiltered comedy. Series creators Trey Parker and Matt Stone continue to churn out new episodes of the series that first premiered in 1997. New episodes of South Park air bimonthly on Wednesdays at 10 PM EST on Comedy Central, followed by next-day streaming releases on Paramount+. Those who want to binge-watch all six new episodes in one sitting will have to wait until the season 29 finale arrives on November 25. Since each episode is only 22 minutes long and typically is relevant to current events, it's best to make South Park part of your streaming rotation throughout Fall 2026. Lioness Lioness season 3 has been on a tear this summer on Paramount+, holding the streamer's #1 spot shortly after its premiere back on August 2. After seven weekly installments, Lioness season 3 will finally conclude this Sunday, September 20, with official confirmation of a season 4 still to be determined. The Taylor Sheridan spy action thriller has emerged as one of his best series of all time, partly thanks to his stellar ensemble led by Zoe Saldaña, Nicole Kidman, Morgan Freeman, Michael Kelly, and more. Lioness season 3 has found Saldaña's protagonist, Joe McNamara, a highly trained and trusted CIA operative who leads a top-secret program, in more danger than ever, forcing the series into new narrative territory. Part military action series and part political thriller, Lioness might just be Sheridan's most well-written series, even though other shows like Landman have been bigger hits. That said, Lioness season 3 has achieved new series-high numbers in viewership and now is the perfect time to start watching the series if you haven't already. MobLand There is no better show on Paramount+ to watch this weekend than MobLand following its season 2 premiere on Friday, September 18. After waiting 15 months since its season 1 finale, MobLand fans can finally rejoice as the second season premiere is ready to be watched tonight. MobLand season 2 was welcomed back with a perfect 100% Rotten Tomatoes score from critics, suggesting that this sophomore effort is already shaping up to take the acclaimed crime thriller to even greater heights. MobLand season 2 returns with its biggest A-list stars, including Tom Hardy, Pierce Brosnan, and Helen Mirren, as well as a fantastic ensemble that is expanded even further in season 2. Critics attest that the series has evolved in both scale and scope, giving Tom Hardy's protagonist Harry, an experienced fixer for the Harrigan crime family, even more problems to deal with, both internal and external. With its season 2 premiere, MobLand is bound to be one of the biggest streaming hits on Paramount+ this weekend and for Fall 2026, making it the opportune time to start binge-watching season 1 or dive into its brand new season 2.
