That's a good point. One of the things people struggle with I think is understanding the full scope of what was considered Greek and over what period of time. That and the competing representations of figures and the timeline of events means it really is like taking in a series of vignettes, each with its own take.

Stephen Fry did an excellent job making an updated and streamlined version of the mythology, effectively choosing from the myths what to accept as cannon in his retelling. If you haven't read his books I would recommend them as being a wonderful story. He also narrated them himself on audible, which were also excellent.
