I work at a Regal Cinemas in my area. The most I can tell you is that it all comes down to who the general manager is. The one I work at is around 10 years old and only has a few true stadium seating auditoriums, the older ones that were not redone still have good sound but that suffer that small porno theater feel that you guys described, still is a decent place though. In my area we have a nicer Eastern Federal theater with all around stadium seating. Obviously the bigger one gets alot of the bigger movies because they outbid us a lot but ours still gets few of the bigger movies. Seems like Regal is picking up a lot of steam and buying chains out lately though.
