I saw the whole BS-series shortly after its appearance in 2005-2009 and was baffled by its strong plot, superb acting, realistic character building, thematic engagement, overall maturity, sense of nuance and philosophical depth. Now, some ten years later, I enjoyed watching it again from start to finish. BS has lost none of those qualities and attraction. BS set a new standard for scifi series and remains unbeaten (unfortunately).
