Hachi: A Dog's Tale can be good for learning English if you already understand everyday conversations and want more consistent practice. Lines are generally delivered at a comfortable pace for regular listening practice. Most of the language stays fairly accessible, so learners can spend more energy following the scene than decoding difficult words (more than 77% of the words come from common English vocabulary). Because the plot is fairly straightforward, learners can focus more on the dialogue than on figuring out the story. If your English is close to A2/B1, Hachi: A Dog's Tale can be useful for building listening confidence.
