The notion of an Icelandic elf whisperer who communicates with invisible spirits and sprites that are tucked into a parallel existence in nature might give one reason to pause and perhaps scratch one’s head. Berkeley filmmaker Sara Dosa knows that well and acknowledges that her latest fascinating documentary “The Seer and the Unseen,” available to stream and popping into Bay Area theaters for special screenings in the days ahead, might well have its skeptics. This week’s Pass the Remote is dedicated to Dosa’s film, which delights in making us appreciate the hidden attributes of nature and the important role of the in-need-of-protecting silences that exist there.
