The Muvico at Arundel Mills is an enormous theater complex, with 24 screens, large theaters, plenty of space. With so many screens, they offer movies all the time--starting early, ending late, with shows almost every hour. Employees are helpful and efficient--ticket rippers are always nice, box office sales people are usually not particularly friendly. Prices are normal for the area.
However, since it's located in the mall, it tends to get crowded--you can go shopping and just stop in for a movie, which a lot of people do. It's also subject to the poor parking situation at the mall--all lots, no garages, it's ridiculous trying to park on the weekends, and I won't set foot there in December.
