“Mary Poppins Returns” sets a Hollywood record for the longest time divide between installments, with the sequel arriving 54 years after the original “Mary Poppins,” which helped cement star Julie Andrews as a screen icon, delivered Disney a monster hit, and won the studio five Academy Awards. Disney took their time to deliver a follow-up that could do walk and talk like the original picture, forced to find a way to bring Mary Poppins back to screen without the help of Andrews, who doesn’t return for the new adventure. Instead, there’s Emily Blunt, and she’s an amazing replacement, handling elegance, cheekiness, and musical numbers with impressive grace and screen magnetism. It’s the rest of “Mary Poppins Returns” that slightly underwhelms, finding the production unable to find the line between continuance and rehash as it plays a very safe game of nostalgia, only here the effort has been fluffed up considerably by Broadway influence.
