Again I haven't played the game but the comments from the video seem to reflect it a bit. The people who enjoyed the game seemed to go looking for deeper meaning in any context from the game. The people who didn't like it felt that it was all build-up and no pay-off.
What I love about this in a general respect, I have a personal anecdote that surrounds the topic of "Going for an artsy ending"
My 6th grade history teacher wanted us to pretend that we were forced to flee from our houses during (some event in history, honestly don't recall) and write a journal about the events that happened. What I did was start the journal like things were normal and then when we were forced to flee, I had left my journal behind so it stopped mid-sentence.
I thought I was being super clever by really placing myself in the circumstances. I mean if you were forced out somewhere, during the chaos would you really remember to take a journal?
She gave me a F for that assignment.
Yeah I've tried to subvert some assignments in my day...usually doesn't end well, they're looking for your take on the situation, not thinking outside the box.
