I've had plenty of bad experiences at theaters, but not those 2 theaters, they really strive to make the experience a good one for the customer. The theaters I had bad experiences in, I don't go back to. Simple as that.
In my experience, the theaters with the cheap prices are that way cause it's the only way to get people to come there, either the experience at that theater is sub par, or the populace doesn't have the means to pay the standard ticket price, cause trust me, if the theater could stay afloat and charge $12 a ticket, they would.
