Don’t worry OP, there are multiple sequels to Avatar coming out over the next few years, that’ll save you from having to watch remakes.
From Wikipedia:
Two sequels to Avatar were initially confirmed after the success of the first film; this number was subsequently expanded to four.[303][304] Their respective release dates are currently December 18, 2020, December 17, 2021, December 20, 2024, and December 19, 2025.[32] Cameron is directing, producing and co-writing all four; Josh Friedman, Rick Jaffa, Amanda Silver, and Shane Salerno all took a part in the writing process of all of the sequels before being assigned to finish the separate scripts, making the eventual writing credits for each film unclear.[305][306][307][308]
Filming for the first two sequels began in September 2017 and is expected to continue into 2018;[309][310] the filming of the following two is expected to start as soon as Avatar 2 and 3 wrap filming. Sam Worthington, Zoe Saldana, Giovanni Ribisi, Joel David Moore, Dileep Rao, and CCH Pounder, are all reprising their roles, as are Stephen Lang and Matt Gerald, despite the deaths of their characters in the first film.[311][312][313][314] Sigourney Weaver is also returning, although she stated that she would play a different character.[315]
New cast members include Cliff Curtis and Kate Winslet as members of the Na’vi reef people of Metkayina, and Oona Chaplin as Varang, a “strong and vibrant central character who spans the entire saga of the sequels”.[316][317][318] Seven child actors will also portray pivotal new characters through the sequels: Jamie Flatters, Britain Dalton and Trinity Bliss as Jake and Neytiri’s children, Bailey Bass, Filip Geljo, and Duane Evans Jr. as free-divers of the Metkayina, and Jack Champion as a human.[319][320]
Although the last two sequels have been greenlit, Cameron stated in a November 26, 2017 interview: “Let’s face it, if Avatar 2 and 3 don’t make enough money, there’s not going to be a 4 and 5”.[318]
