I considered not rating Farewell, Friend at all because most of the runtime my mind was just "???????". I can't say this is some excellent piece of cinema that everyone has to see, but I also can't say I wasn't fascinated and intrigued the entire time.
The dubbing is so monotone it almost feels like a creative decision. There are random scenes that really have nothing to do with the plot. So much makes no sense. It's odd because it almost feels like these choices were purposeful, but I doubt they were. These decisions make the film strangely riveting.
There's also a scene where Alain Delon's character is crawling through a vent-type of space with a paper he lit on fire and I thought to myself, "Did Die Hard get inspiration from Farewell, Friend?"
