Re-hash

Was simply a take on the old cult classic - "The Wicker Man". If you've seen that one; either the original version of it, or the one with Nicholas Cage - then "midsommer" makes more sense. Though in The Wicker Man, the back story is more developed and integrated into the telling.
Insofar as the premise goes, summer solstice celebrations are universal. That's what Midsummer, and the Maypole is all about. In Scandinavia the sun stays up virtually the entire day at this point of the sun's cycle. Human sacrifices were well known to take place in order to ensure success of the following years crops.
The ancient Druids had the practice of burning humans alive in a tree made of wicker.
Not quite a horror movie from that standpoint. But, this was not unwell made.
