As big as this town is for independent movies, there's not a great abundance of theaters that carry them. The Arbor Cinema, however, has always stayed true to their independent spirit. They are also never too crowded and I've always had a great experience here.
If you're planning to attend a movie during a high-peak hour on the weekends, do try to be there a bit early because parking is sometimes an issue. Specially if there's a hot movie coming out - and since Arbor's usually the only one playing it - also plan on getting in line before buying your ticket.
