In this movie, Nobita brings a young tree home, where Doraemon gives it the ability to walk and think. I found most of this movie quite pleasant: the visuals are beautiful, the interactions between Kibo and the main characters are charming, and the plant planet they end up visiting is interesting... but then the climax happens. I'm not even going to try to explain what goes down. Suffice it to say, however, that this is almost certainly the most baffling Doraemon movie ever.
It's not only that the plot is resolved in such a bewildering way, but also that intriguing setup from earlier in the movie is never given any proper followup. Why did the plant aliens need Kibo specifically to power their superweapon? What did Jii the mushroom elder, who apparently is actually the personification of the entire planet, mean when he said that the plant aliens stole their superweapon from him? (We can guess, yes, but it's odd for the story to hint multiple times at a seemingly important history that is never elaborated on.) That's not to mention all the promising characters who are introduced only to be given disorganized character arcs, or simply make no impact on the remainder of the plot. All in all, this movie very much reads as an attempt at making something artsy and profound but then falling short.
