I watched Mr. Roger's Neighborhood when I was young, and I loved it. It was one of the few kids shows that wasn't animated, and it taught important stuff that young-me had always wondered about. It was quality kid's television programming that I can still go back to, watch, and enjoy.
But Daniel Tiger is not anything like the show you may remember from your childhood, if you grew up with Mr. Rogers.
It is, more than anything else, an insult to Rogers and his show. The characters are annoying and have absolutely no depth, as well as a serious personality deficiency. There is no real conflict, unless a mild debate over where to hold a picnic counts. And it doesn't.
The flimsy morals are shoved in the viewer's face repeatedly, half the time through the most annoying and repetitive songs on the face of the planet.
The people behind this show clearly know their target audience is very young children, and they're aiming directly for them with absolutely no consideration for the parents who may be forced to sit through an episode with their toddler.
Please, just pass on this horrible Rogers' knockoff, and instead sit your kid down in front of the original Mr. Rogers' Neighborhood, which you could probably find with a quick Google search. It will provide them with infinitely better TV than Daniel Tiger's Neighborhood ever could.
