Let's start by getting one thing out of the way; this is no 1/10 (however many films the critic claims to have seen). Film making is all about story telling - and Schyffert/Brandelius certainly do that.
They also venture into a, relatively, new format and at times push the envelope of filmmaking. However... bold and innovative as "Spring Uje, spring" may be - it reaches nowhere near excellence. It's low budget and makes no apologies for being so. But somehow it feels like it's a "dead end concept" - one where no amount of further funding would have delivered a home run.
The end result is quaint, at times slow and often borderline childish. But it is reasonable, and certainly innovative, storytelling. If you can get into the format - it delivers beyond your average Hollywood "standard".
For the cineast it delivers a few novel takes alongside a few more "don't dos". Commendable though the approach is; the shortcomings feel superior in number to the good moments. By all means watch, but it may be an acquired taste - and those with such acquisitions are likely find a few flaws.
