There is no effort in the writing. The writing comes across as cookie cutter and bland, being nothing more than a cash grab on the excitement rather than trying to be something. While Jack Black wouldn't have been a bad choice for an animated version, the writing makes the film feel more like a Jack Black parody than a Minecraft adaptation. The film simply fails to capture any essence of the magic of Minecraft.
The art style is disappointing. The art style makes it seem like the production team has never played Minecraft. There are many inconsistencies with the game, and trying to make the squareness of Minecraft an artistic choice in a live action setting was not a good move. The cgi is nothing special, and makes the actors look out of place, rather than using CG models.
