There were 6 Thin Man movies in all, all good. I liked "Song" least, though. I liked the others in this order (first listed being the best):
¶ After the Thin Man -- w/ Jimmy Stewart
¶ The Thin Man
¶ The Thin Man Goes Home (though most critics were cool to it).
¶ Shadow of the Thin Man (about horse racing)
¶ Another Thin Man (actually, I liked this one least).
