It was interesting movie.

At the beginning, I was not impressed by main protagonist, I guess we can say I had a false first impression of him.
(?Movie producers, I see what you did there?)

But after watching further as movie slowly progressed,
you get to know more of his character, how he thinks and questions things around and what makes his unique personality.
Later, after revealing his story, you find yourself feeling bad for him and also rooting for him to find some closure and move on with his life after loss of his little son.

I enjoyed the story, It was nicely done with bit of sad and sometimes funny feelings of nostalgia.

I hoped he will also help on other hand his swimming instructor, but that would be too perfect ending so I like it much better this way.?

P.S. sorry for my horrible English, I tried my best ?
