What I don't think many people understand is that the "recycling" of themes isn't really done on purpose (more often than not, anyway). There are certain musical sensibilities that are inherent to a composer whether they like it or not—it's not something that's easy to escape. It'd be more surprising if a composer's scores didn't have anything in common.
