i agree he is overlooked especially as his first three films were masterpieces.
One of my top 5 directors, not to say i liked everything he's done. I think his first three Films are 5 star and showed at the time he was the best around. A Hole in the heart was slightly disappointing at the time after his first three films (its grown on me over the years) but Container was an Art exhiibition trying to pass itself off as a feature film. Mammoth was ok but nothing special. Hopefully he will find his feet again cause he's a special talent.
An overlooked director whose work I find not only moving, but almost necessary to see.
