Contains much of what would be elaborated later.
It has the 'theatre', the 'island', the 'foreboding', 'death', oh, and of course wild strawberries.
The camera work is compelling, and reminds me in its harshness of some of the bleaker Bergman output.
It also has a classic banal death - name three films where a central character dies in such a banal manner, I dare you. The banality of the circumstances reinforces the banality of death (and life) itself - quite shocking.
