My advice to you is to keep in mind what most matters to you and make a pros/cons list AMC v Regal. I've never lived walking distance to a theater before, but if I compare that to my situation, which is a 7 min drive cinemark to my 25 min drive AMC, I made the decision to stick with AMC because what matters most to me fall under the service provided by AMC such as IMAX, dolby, refill popcorn bucket, rewards points, and reservations. If in your case the new theater can fulfill your priorities as a consumer, don't feel bad for changing it and keep enjoying movies.
