Because (Yellow) got all the attention and remains the game changer, there doesn't seem to be a lot of love for its companion piece, I Am Curious (Blue). I like it about the same, for different reasons. Knowing the two versions were originally envisioned as a single, very long film might suggest that (Blue) both prefaces and finally book ends (Yellow), but the middle part does seem an entirely different journey for Lena. The documentary elements are different, attacking different issues than the first film, more in line with the introspective mood of this second effort. (Blue) is narrated by Lena - the actress, not the character, though the line is still blurry - as a journal or travelogue, and the subjects tackled feel less political and more societal (how women are perceived by men, for example, and questions of family). So it's a bit less opaque, more intimate, and more straightforward. And it does fill in some gaps that can be felt in (Yellow), we get a better sense of who some of the characters are. Since (Blue) came out a year after (Yellow), it uses that opportunity to include the reaction to that film, exposing uncomplimentary letters sent to the film maker, not to showcase the international furor, but Sweden's own conservatism. I was reminded of Anno publishing death threats in The End of Envangelion, so whether or not it's considered the weaker film, (Blue) is still influential.
