Overall, I enjoyed Men in Black 3, but it was still a disappointment on some levels, and aspects of it left a bad taste in my mouth.
SPOILER WARNING: I'll be discussing the entire plot, including the ending.
The Good:
So Agent K is "getting too old for this", and so is the 65-year old Tommy Lee Jones. The solution? Create a Time Travel plot that requires K's younger self (Josh Brolin) to take center stage. Simple, clever and elegant. If the franchise continues, I'm sure the writers will eventually bring Brolin back.
Jones, Will Smith and Josh Brolin all played their parts well. In particular, Brolin's impersonation of Jones was astonishing.
Griffin is a very likable addition to the series, thanks to Michael Stuhlbarg's charming performance.
Even though I guessed "The Colonel"'s true identity early on, his storyline was still heartwarming.
When J is the only one who remembers Agent K, the You Have to Believe Me! cliche is largely avoided, as Agent O figures out what's going on quickly.
The revelation about Andy Warhol was kind of cute.
The Bad:
Boris doesn't get the necessary Character Development to make him a truly memorable villain (I speculate why below), and his Catchphrase quickly becomes annoying. However, I liked the confrontation between his past and present selves.
I like works where the heroes believe Thou Shalt Not Kill, or at least use deadly force only as a last resort. However, in MIB 3 the plot is crafted to make killing Boris the heroes' only realistic choice, and no one has a problem with it. (This may be why Boris isn't fully developed—the story depends on him being little more than a rabid dog who needs to be put down.)
Even worse, no one has a problem with entire Boglodite species dying off (for reasons that are never adequately explained). The film's morality is that they're Always Chaotic Evil, so good riddance. (I thought the secret K was hiding was his guilt over helping to destroy the Boglodites, which J's intervention would have allowed him to make up for. I wish the film had done more with this.)
Final verdict: MIB 3 is well worth seeing, but don't think about it too much.
