I tried watching the film when I was just getting to know Palsa's works, and back then I understood nothing of it and didn't watch it through. I did re-watch it in full later on, and while I appreciate it exists, I'd guess it offers very little to anyone who isn't fairly familiar with Palsa best known comics and paintings and the "highlights" of his life beforehand. It's very fragmentary indeed.
There's a new Sarjakupla podcast episode about Memoirs Of A Pensioner, the English translation of Palsa's Eläkeläinen Muistelee comic. The podcast itself is in Finnish though.
