Matt DeTurck’s review published on Letterboxd :
It had some lovely moments, and at times I liked its overly melancholy tone. But it was also SO melancholy and desaturated, so I'm conflicted. The adult-relationships are a bit thinly-sketched, the plot is surprisingly "Hook," and not everything works. But it's got a good heart, the Hundred Acre Wood feels very REAL, the characters are impressively animated, and there are some interesting treatments of the "world" which I think are interesting. It's tough to be mad about seeing Ewan and Hayley.
Jim Cummings doesn't get enough recognition for his fantastic vocal work, but his line delivery as Pooh *MAKES* those lines work.
