Here's my honest opinion:
While the story was predictable, that was kind of the point. It is supposed to be just one of many Minecraft stories. For some that story is an ender dragon, some epic tale, while for others it's just goofing off with friends.
This film is a breath of fresh air in my opinion. This is a movie where you can just sit down, grab your popcorn, and watch it unlike movies which sacrifice enjoyability for a good story. The jokes landed well, the deliveries were perfect, and the CGI, surprisingly, wasn't half-bad.
However my one criticism to the movie is that, while it is supposed to be goofy, some of the "goofiness" was borderline unironically bad.
Other than that an amazing movie, solid 7 or 8/10
