To start with, I got a headache going through this sci-fi venture. The first part was great, second was average but this was plain bad. I owe much of its commercial success due to Smith's star power (his last 10 films have grossed over $100m globally!) and starting the streak is MiB 2. Critically, I have no idea how this was rated 'fresh' on Rotten Tomatoes.
MiB 3 follows Agent J (Smith) going back in time to save the entire planet from an outerworld invasion and his partner Agent K (younger version played by Josh Brolin and the present by Tommy Lee Jones). My main positiveness of this feature is Brolin's acting skills. Seriously, when you catch him at first sight he is the splitting image of the Jones' depicted Agent K. He would've gotten an Oscar weren't this film way below Academy Award status.
Some lines are entertaining and witty especially when Smith enters the late 60s New York but nothing seems original. Wisecracks are lame and the sense of humour, is well, senseless. Smith's theatricals are boring and except for Brolin there is no silver lining in the picture. All other actors except for the 3 in the poster are uninspiring and unwanted for any potential sequel (which has been confirmed).
Plus the villain is disgusting and tedious. There was no hardwork done on his costume design or character innovation. Other aliens shown were quite few a number with good designs but highly weak personalities unlike what MiB is known for. And most of the cult characters, like Chief Zed and Frank the Pug (extraterrestrial dog agent). This goes to show that adding more humans to the mix like Agent O played by famous English actress Emma Thompson was disastrous.
The plot is boring and even the back-in-time America is badly showcased and the 70s America was given more justice in this year's Dark Shadows. The ending was good but that does not manifest the one hour and 40 minutes of suicidal viewing.
Let me also add that this is one of the worst sci-fi ventures I've seen of all time. If you wish to have an alien adventure this year it's better you try Disney's John Carter despite its flop status.
In the end, MiB 3 might be the highest grossing film in the series outside North America but it is the worst according to my book. It was also shown in 3D which by watching the 2D version you can say was completely unnecessary. It is also made the biggest IMAX Memorial-Day weekend and I guess Smith can achieve anything (at the box office).
Rotten Tomatoes: 69%.
