Considering it's the only theater on the island, it's not bad. If you don't mind driving 15 miles north, you can go to the Mall of the Mainland theater which is much newer and cleaner. Regarding this theater, the screens are small, the chairs are uncomfortable and the theaters are usually dirty. However, there's hardly every a large crowd, even on opening night, and the prices are decent by today's standard.
Bottom Line: If you want to see a movie right away without driving off the island, this is your only choice.
