The Secret in Their Eyes is a real gem of a film and justifiably won the Oscar for best foreign language film of the year in 2010. The strength of this film is in the storyline, the way each piece of the jigsaw is subtly put in place so that there are no holes left at the end is quite beautiful. You may need to watch it a second time to pick up all of the cues because unlike most Hollywood films it Juan Jose Campanella assumes that his audience is intelligent and so doesn't feel the need to hit you over the head with repeated plot lines or take time to re-cap for those that are too slow witted to keep up.
The acting is excellent, dramatic, comedic and superbly underplayed. Those reviewers that bemoan the lack of Hollywood production standards I feel are missing the point somewhat. A stage play isn't as slick as a multi-million dollar Hollywood film but is no less valid. This film's beauty is in the acting, the story and actually the production is really quite slick, probably akin to Hollywood in the 90's.
The end to the film is as stunning as it is haunting. I really didn't see it coming although all the clues were there. Hollywood could/would never conclude a film like this. All the strands are pulled together but in such a surprising and chilling way. I rate this film very highly. When weaving together different genres it can be difficult to keep focussed but this film achieves it brilliantly, mixing unrequited love, detective and comedy is a bewitching brew.
I give this film five stars; I couldn't think of any improvements that would make it better.
