I have omitted several plot points including a major spoiler from my comments as I didn't want to give too much away. 

Normally I like the use of non actors but I got the feeling that Marcos found great difficulty in actually getting into the right mind set for his role which would probably have been difficult even for an experienced actor. 

It is an awkward film but as I said earlier, nobody left the screening, in fact everyone sat through the credits which is pretty unusual in itself.

I'd definitely recommend it to you A and arsaib4 along with a few others, I only wish I'd had someone to discuss it with straight after the screening. 

Cheers Trev.
