First off, I was a muffle school "punk" in 1982, so I couldn't resist catching a screening of We Are the Best at the Jeonju Film Festival (Korea). My previous experience with Swedish films has been limited, and resulted in spells of sleep (the scenes of Swedish TV in this film were reminiscent!).
The young actresses were amazing! Real, infectious. . . brilliant! The story-telling and script were first-rate. The filming fit the material perfectly. I could appreciate this both as a 40- something adult now and as a compatriot of the main characters from that time period-- even if I experienced adolescence half a world away.
It's a feel-good film, and serious issues are framed in the most palatable way-- but the movie makes no pretensions and it it was it is, and that is a first-rate film, great for all ages, that has everyone leaving with a smile!
