4/5
Men In Black 3 is the sequel that nobody asked for and that everybody was surprised by. It offers an origin story for both leads that brings complexity and depth to the characters, making them more authentic and infinitely more heartwarming. You wouldn't expect that from a simple sci-fi action comedy--and you wouldn't expect for it to be done so expertly--but it gives us all that on top of everything else that makes the series so watchable. Past all the superfluous and silly special effects, past all the precisely-delivered one-liners, past all the action and excitement, the movie leaves an indelible mark in your memory because it plucks the heartstrings so powerfully. Honestly, seeing that finale just made my heart drop a little. How can you not feel something when you discover what turned Josh Brolin into Tommy Lee Jones? That small, perfect moment at the end is what makes Men In Black 3 the best of the series. And what makes me want to see it again and again.
