I scraped all of Fandango’s movie listings

The cheapest movie ticket in the country? CMX Brickell City Center in Miami wins the title of most expensive theater in the country: a ticket on Fandango will set you back $26.75 or $28.99, depending on the day and format. Independent theaters and smaller chains (those with 30 locations or fewer) make up over half of the theaters listed by Fandango.
