Per Enström’s review published on Letterboxd:
As a non American I don't fully appreciate the vast amount of work that has gone into making both Tom Hanks and the sets and scenes from Mister Roger's show as detailed and accurate as possible. Some might even call it fan service. Sometimes the film stays with the show for too long. And we get it, he's really, really nice.
All in all though, both Hanks' and Matthew Rhys' performances are good, the framing story is nice, the accuracy is great, and it has a great soundtrack. The way Mister Rogers breaks the forth wall to not only give therapy to Lloyd Vogel, but also us, is a great move that actually works. You can't help but do as he says when there is an actual full silent minute to reflect. But despite that, it just isn't anything that special. Worth a watch.
