I thought it got the basics right and it wasn't too ambitious in anything and the mix of performers, characters, and writing worked. Special mention should be made of the skills exhibited by the Make–Up Department.
The format of the screenplay all but ensures unevenness but it is a film that should be commended for its intentions and one that most of us should see at least once.
The cultural barriers, especially the need to use a translator, also make it a frustrating watch but they do help to get the point of the screenplay across.
