Not so good as previous trilogy, yet not so bad as critics say. Its story is aggressively mediocre, but the chemistry between erudite Tessa Thompson and meaty Chris Hemsworth bursts out so hilariously this film is saved from the painful fiasco F. Gary Gray shows off. Still, the aliens, which should be the main point in the film, are charmless like a half-baked excrement, so it is just slightly more than mediocrity.
A reviewer for The AV Club once remarked that the worst movies aren't necessarily the ones that are actively bad. No, the truly awful movies are mediocre, the ones so bland and forgettable it's like eating unflavoured porridge. Men In Black International is the most poridge film maybe ever. Nothing sticks out, nothing is actively offensively bad. It's just bland. It's a black hole of charisma. As RuPaul said, Meh.
