The second half of the movie is all about applying the frolic of the first half to the reality of day to day life...and well worth looking forward to, much less sitting through. Bill's "idea" is to seize every opportunity, much less day, and Cora's "practicality" is the deadening effect being reasonable at all costs can have. Henry O'Neill was a great find, and you'll notice him more often than you'd think once you've identified him: as Bill's worst enemy at the beginning of the movie, it is he, as Cora's dad, who brings not only the couple but the theme together by the end of the movie. Deeper than it appears, it is charming through and through
