This is a great idea. I have recently heard that the movie Clash of the Titans remake has no "soul". The movie is all about Greek Mythology, the journey of the hero, you know... but these days movies are all about explosions and CGI to the max. In the process it loses it's soul. Mythology is about the richness of the human experience, the trials and tribulations we go through in life in small and large ways, the personal and the global.
This is a tough one... I don't have any favorite gods that I know of. When I think of archetypes I think of how the tarot explains them in pictorial, mythological detail.
I know some people actually relate to a god through their own personal journey and it's like that of astrology too, how the planets are the symbolic forces that flow through us, and they are referred to as gods in their own way too.
Mercury for me has been a favorite, the archetype of the messenger to the gods. I felt, and do feel a particularly strong connection to Mercury because I feel like I have a strong connection to the Divine, in my own way (sure it could improve) so let Mercury help me get my messages to and fro the Divine Because I like Thoth, I like Hermes Trismegistus, and Mercury, they are all interrelated to one another I feel an affinity to learning, magick and the mysterious connection As above, so Below brings us that connection.
When I think of an archetype, The Fool, The Hero's Journey come to mind as probably the most well known, or spoke of. I watched the more recent Superman movie recently and the connection they made to the Hero and Christ as a Savior was quite obvious.
