While the sequel is similar to Mary Poppins in a lot of ways, it also adds something new to the beloved story. Since the film takes place during the 1930s Depression era in London, the story has a few darker undertones. Jane and Michael are also very different from the cheery kids we met in the original film. Now that they are adults, they are facing much more mature problems, like the loss of a loved one and financial struggles. It's interesting to see the memorable story through a whole new lens, and it ultimately helps set the sequel apart from the original.
