What is the Minecraft movie about?

"A Minecraft Movie" is of course based on the iconic sandbox worldbuilding game that debuted in 2011.

In an official synopsis, Warner Bros. describes the plot as four misfits who end up in the cubic world of Minecraft and must protect it from enemies that include the game's Piglins and Zombies while on a quest to return home.

Mixed reactions to 'A Minecraft Movie' teaser

Many longtime Minecraft fans felt the film's visual style was an unwelcome departure from the pixelated world that had made the game unique. Instead, fans expressed disappointment for the perceived over-reliance on CGI and the unsettlingly realistic creature designs.

Polarizing viewpoints took over social media, and even some news outlets – with one writer at Esquire complaining that the trailer release "ruined my week." Another at PC Gamer declared that the Minecraft film may supplant the widely-panned Borderlands adaptation as "the worst thing to happen to cinema in 2024."

On X, formerly Twitter, some users compared the visuals showcased in the trailer to an AI-generated rendering.

Others didn't like the blend of live-action and CGI.

Michael Edwards, a voice actor, criticized the the choice to adapt Minecraft as a live-action film instead of making it an animated movie.

“I do not understand the decision to have live action actors in the Minecraft world, when Minecraft translates so incredibly well to animation," Edwards posted on X. "The green screen here is horrendous.”

Others on social media were horrified by the animal designs, which transformed the games blocky animals into creatures that bore an unsettling resemblance to their real-life counterparts.

One user on X even compared the creative choice to the fiasco surrounding the unveiling of the movie-version of Sonic the Hedgehog, which forced animators to go back to the drawing board in 2020.

"Realistic animation will ruin us all," X user TommyInnit proclaimed.

And then others were simply baffled by the wig choice for Momoa.
