The big Warner Bros. streaming experiment continues this week with the studio's newest theatrical genre release simultaneously hitting the HBO Max streaming service along with the big screen. Plus superheroes, ghosts and zombies — let's dig in.

The big story this week is the film premiere of Reminiscence, which arrives on HBO Max and in theaters. The near-future film stars Hugh Jackman as a detective investigating his own memories. It's from a former Westworld producer and feels right at home in that smart and sexy corner of the genre. Elsewhere in major premiere news, AMC's undead juggernaut The Walking Dead is back for the beginning of its super-sized final season (which is expected to stretch well into next year with some mid-season breaks).

On the finale front, one of the best new shows of the year is wrapping up its debut season, as Superman & Lois makes its last stand against a rogue Kryptonian trying to take out Metropolis and Smallville. The show is fantastic and well worth a catch-up during the offseason if you missed it from the jump. Digging deeper, SYFY has a new SurrealEstate; Disney+ has a new Marvel's What If...?; Fox has a new LEGO Masters; HBO Max has a new Titans; and Showtime has the latest entry in its UFO docu-series from producer J.J. Abrams.

Check out the full rundown below.
