Dylan Gorzen’s review published on Letterboxd:
For a movie called Piglet's Big Movie, it's hardly big or anything to do with Piglet. It did have a cute callback to the Tigger Movie, the message was decent, and the ending was quite wholesome. But the movie is mostly just flashbacks to Piglet's deeds and just comes across as episodes to The New Adventures of Winnie The Pooh. On top of that, Piglet is not very much in the movie if you remove the flashbacks which begs the question, where was he while his friends were looking for him? I also wasn't a fan of the songs from Carly Simon even sometimes taking me out of the moment. The climax had the same problem as The Tigger Movie where characters had to survive danger which I felt like it didn't need to be there. Not awful by any means, but it's doesn't feel like it needed to be a movie.
