5 best new to HBO Max movies in March with 90% or higher on Rotten Tomatoes

HBO Max added nearly 100 new movies to its already impressive library at the start of March 2026 (89, to be precise), meaning movie buffs have a ton of new releases to keep them occupied throughout the month.

Now, if you ask me, that’s a pretty daunting number of films to sort through, especially when you consider all the other best streaming services have also bolstered their ranks with new additions, too. So, if you can’t quite face sifting through everything new on HBO Max in March 2026, allow me to step in. I’ve just scrolled through that list of new movies and picked out five that have earned a minimum of 90% or higher on the review aggregator, Rotten Tomatoes, which is usually a pretty strong indicator that any given movie’s worth a watch. Sure, you can’t guarantee a high score will mean any of the below picks will match your personal tastes, but a 90% or higher on RT at the bare minimum means most movie critics liked what they saw.
