agreed, and thank you for bothering to reply cos diversity in opinions is what makes this discussion interesting
as for the philosophical stuff, i can only speak on behalf of myself (obviously), and for me a lot of it in this movie comes from the cultural aspect. for example there are a lot of scenes which centre around scarlett johanssons character (charlotte), in particular, quietly observing japanese people and their culture. and because of the way the film is shot, wherein everything is made to look so smooth and elegant, it emphasizes the idea of how there is an ever present beauty which is to be found in difference, and life.
just the fact that i dont know what she's thinking when she witnesses, say, for example, in the scene which i previously mentioned where she travels by train to the temple, and sees the japanese bride, but i can tell by the expression on her face that she is amazed and happy, coupled with the fact that the way that scene's shot is so beautiful, is what gives it that ambiguous/ philosophical / humanitarian air. the experiencing beauty in difference, and life, idea.
also the fact that there wasn't special emphasis on the strong turbulence which individuals often experience upon having an affair. or the fact that given the way the film ends, where we don't know what happened between bob and charlotte after they parted ways, is actually something that i like - for it gives life and our experiences in life an inherent beauty, and intrigue, yet at the same time a certain meaninglessness. that is, through the absence of strong emotions the film opens up a lot of room for subjectivity to play its creative part. and it really draws you in to just sit back and observe the world like both characters have a tendency to do.
so, yep. also, when writing that last paragraph i just thought of something... how the fact that charlotte is a philosophy major may also have some symbolic relevance to these aspects of which i speak?
