The host (Nina) and Star are engaging and soothing at the same time -- a difficult thing to do and they do it well. The cartoons they show in between segments are also soothing and calming. There is nothing sweeter than the goodnight songs sung to hush the fish and the little sproutlets watching. I also like how you don't have to watch all 2 hours (which I would not want my son watching 2 hours of TV) but you can pick up at any point and feel like you are getting the full experience. PBS Sprout really does preschool programming well and this, in my opinion, is the cream of the crop.
