Among some of the more questionable choices that Amazon Prime is adding to its roster in May, there are some very good films. Among the good ones are classics, such as “A Christmas Story,” “Planes, Trains and Automobiles” and the Naked Gun trilogy. Amazon bolstered its James Bond collection by bringing back a whole bunch of titles including “Thunderball,” “Goldeneye” and “For Your Eyes Only.” Then there are some all-time greats like “Gone with the Wind,” “Wizard of Oz” and “A Fistful of Dollars.” That’s a whole lot of quality movies to watch.
