AMC Southlands 16 in Aurora - The Southlands 16 Theater is quite large, supplying some nice options for movies Aurora, Colorado. While some complain about the high prices, others say that they compare with other large theaters - which one should plan to pay if looking for a theater with quality-grade seating, sound and picture.
Century Aurora 16 Theater - While the reviews on this theater are mixed, generally they're good. The main positive point appears to be the rates of the tickets, and senior citizens are given a nice discount as well. Other negative points mentioned in past reviews include the quality of the picture and sound in one or more of the theaters.
AMC Arapahoe Crossing Theater - While I was not able to find as many reviews for this theater as compared to others, those I read were good - and I agree with them. This is a nice cinema with good seating and standard prices - and generally speaking is a great experience for watching any of a number of movie selections.
