I'm in agreement with you. Incidentally, Lost touched on so very many themes, but if you had to choose just one theme for the meta-theme, it would be "darkness and light." That theme manifests in EVERY character and situation throughout the series. The characters are often faced with circumstances that test whether…

Lost, in turn, was preceded by Babylon 5… and that really helped the particular genre. Lost took it a step further and really blew everyone's minds, but I don't think we can discount B5's influence on serialized dramas. Just IMHO.
