All this week, in celebration of last week’s golden anniversary of the national public TV premiere of Mister Rogers’ Neighborhood, PBS KIDS is pairing five memorable episodes of the wonderful Fred Rogers children’s series with similarly themed episodes of its animated spiritual successor, Daniel Tiger’s Neighborhood. The double features will play daily, one per day, all this week on PBS KIDS, so check your local listings. (Usually, they appear locally somewhere in the 8-10 a.m. ET block.)  Today, Daniel Tiger’s Neighborhood features the dual episode that includes the 15-minute segment “Daniel’s Fish Dies,” which is a new episode, specifically inspired by and echoing the original Mister Rogers’ Neighborhood episode from way back in 1970, “Death of a Goldfish.” If you have young kids, and maybe even if you don’t, make sure to watch, and record, all week’s double features.
