"Mr. and Mrs. Incredible" tells the "story" of a couple of superheroes after they retire, and go to live to a little village in ancient China. And it is "story" because barely anything happens in the movie, which has an almost non-existent story-line to fill the moments till the closing credits.
As said above, the story is basically Sandra Kwan Yue Ng and Louis Koo's characters talking to each other, getting mad to each other and little else, while the running time goes on. But even if the plot lacks, the character's development is really good and almost from the first second, being with these two retired superheroes is lots of fun, even if in their relationship there is nothing new under the sun. It also has to do with the ease everyone acts, even if the movie doesn't ask much from them.
The third act, though, suffers from being overlong, as the plot tries to put the action that wasn't before with a threat to the heroes that doesn't make much sense.
There is also, curiously, a couple of plot strands that get no resolution, which, with a story as simple as the one this movie has to offer, is shocking.
However, this is a charming little movie that lets itself be watched with pleasure.
