I never really got the fuss about Men in Black. The first film was quite entertaining, yet the second was poor. The effects were clever and the aliens were amusing, plus Smith and Jones had good chemistry. But it was never mind blowing.
This third entry could have been a sub-par cash-in or just plain dull very easily. But it is given a significant boost by Josh Brolin as a younger Agent K. He is exactly what you’d imagine the character to be like 40 years earlier. Which means he isn’t much different, and Brolin nails it.
As in the previous films, the aliens and weapons are very imaginative and well crafted. Being a fan of practical effects, I was pleased to see it used where possible.
