I just watched this movie named 'Children of Heaven' (imdb link) . Its an Iranian film made by Majid Majidi. I once heard that Iranian movies known to be simple yet powerful. And believe me, after watching this one, I totally agree with that. I don't want to say anything about this movie as it might spoil the fun. I highly recommend everyone to watch this. I guarantee that you won't regret it.
Here is the link if you want to watch it in youtube.
