Before the movie starts, there is a flashback of what has happened so far until the third movie. As this is the last concluding movie, it is expected to be in fast-paced with lots of twists coming. Yes, it is fast-paced for a runtime of 2 and an half hours with some twists and in the same time, the director manages to pack some dramatic scenes. That is fair since it cannot get all the thrill but no point to it.
The story: It starts off at 2017, two years after the second movie. Friend is still carrying his plan of destroying the world and the heroes are to stop him. The pace moves briskly with some but not all the answer you want to know. Reasonably, I felt the pace goes fast due to the fact I can't wait to see who friend is. With some more clues of who friend is, I decided to wait for the final reveal, not to rack my brain about who he should be. The clock is ticking until the final reveal and all will be revealed. This actually has not much of a mystery not like the previous movies, this goes straight to the point-there is little teasing. Other than that, it is a good movie. The special effects are realistic for a Japanese movie. What more do you want?
Overall: 20th Century Boys is one of the best trilogy and also one of the best Japanese movie I have seen. It has a big budget and it made use of it. It is actually one of the few trilogy in Japan, Japan is not a fan of trilogy. I hope more big budget Japanese trilogies will come out but they should be good. If 20th Century Boys can make a good trilogy, why the rest can't?
