Regardless of context?
I don't think the two protagonists suddenly discussing the ethics and philosophy of war while reloading behind a container would charm audiences that much.
I like some sort of technical/philosophical dialogue, especially when it is correct, as it shows that the director/writer doesn't think that his audience is stupid. For example,I never finished Mass Effect 1, but I liked all the little flavour texts that came in that pocket encyclopedia. The debate between JC Denton and Morpheus in Deus Ex was also fantastic.
But the context certainly matters. It would feel out of place to jam such things into everything.
I'm not entirely sure what you're getting at with your question to be honest.
