speechless... ok maybe not
It's very good takes some time to let it all come down on me, very deep. You asked for the moral and theme and I think it has got something to do with life and death. But I also think it is different for every person and what a person has on his mind at the time he is watching it (so I mean where he/she is in his/her life) so maybe when I would watch it again after 5 years I would look at it differently.
Also it really is some psycho shit like you are doing some expiriment with the people watching this, at least that was also coming up in my head when I was watching the reviews. Making someone watch something like this for a long time would really mess up his mind.
Anyway good job, really would like to see more stuff like this. And you made me write the longest review I ever wrote (I think)
