I absolutely adored this film. It's rare that a musical of this era has numbers which are not only entertaining but also further the plot and characters. The score by Jerome Kern and Dorothy Fields is exquisite, including such gems as 'Pick Yourself Up' when Penny's trying to teach Lucky how to dance and 'A Fine Romance' when they're trying to resist each other in a gorgeous snow scene. Astaire's rendition of 'The Way You Look Tonight' is sweet, enjoyable for its sentiments and not the strength of his singing voice. The pinnacle of this film, though, is the majestic 'Never Gonna Dance' near the end. It not only serves as a visual representation of Lucky and Penny's romance, from their first walk around the dance floor to the Penny's walking away, but it's also a deeply sensual and passionate representation of love as a whole. I could easily watch it for hours and those dozens of takes it took to produce such brilliance was well worth Ginger's poor bleeding feet.
There are plenty of comic moments in this one, plenty coming from Victor Moore and Helen Broderick as Pop and Mabel. I enjoyed Broderick in the generally lacklustre The Bride Walks Out (also 1936, reviewed here) and she reasserts her comedic credentials in this one. In addition, Astaire and Rogers bounce off each other so well that every one of their scenes in a delight, from Lucky's first pursuit of Penny down the street to retrieve his lucky quarter to the finale. The plot, though light, is at least coherent and there are several link backs and pointers that demonstrate that the film was conceived as a whole, for example the trouser gag which begins and ends the story. Perhaps there was too much focus on Lucky's friends at the beginning, but once he got to New York, all that was forgotten.
Ultimately, if a film makes me smile just thinking about it then it's a good one. I haven't stopped smiling while I've been writing this review so take that as your recommendation.
