You know what would have improved this film? Wrestling.
The Wrestler was also about a guy living in a van, but it also had exciting wrestling scenes and it was a much better film.
I actually like downbeat kitchen-sink stories that are part social commentary like Mike Leigh and Ken Loach, but there should be some sort of story, not just moping around on a stony beach, moping around a desert, moping around a stony field etc.
SPOILER: it's impossible to spoil because NOTHING HAPPENS!
Worth watching if you want to feel glad to be living in a European country with proper job protection and health insurance.
