Sure there were few shortcomings. The pace of the movie could've been tightened up a bit, especially at the beginning.  The soundtrack was quite monotonous in most parts.  

But those shortcomings became negligible with many positive notes of the movie.  Acting was above par by all, Nima Rumba shines here.  He flows through the movie very naturally, even better than the main protagonist.  Director did an awesome job storyboarding the plot.  The camera work was beautiful and well edited.

This probably ranks higher than Numafung, which makes it #1 in my books.
