Limitations and critiques The film’s sentimentality may feel cloying to some; it smooths Thurber’s sharper satirical edge in favor of feel-good uplift. Additionally, Walter’s life before the journey is presented as inert almost without nuance—his relationships and job are sketched quickly to accelerate the adventure. Yet those choices serve an aesthetic aim: to emphasize metamorphosis. While purists of Thurber might bristle, the adaptation stands on its own as a contemporary parable.
