If you’re in Philly, there may be something in the Chinatown area, or maybe someone there can give you options so your mom can enjoy a movie out with you. I hope you find a solution.
That said, you should go see Project Hail Mary, it’s fantastic. Maybe take a friend if you don’t want to go alone, but I’ve gone to movies by myself plenty of times and I would have gone alone to this one if I hadn’t dragged my partner to opening weekend.
