Almost dull if you've gone out of your way to read the theories and analysis that have been done by fans for two decades, yeah. I'm sure the people who haven't will disagree with you. If you know anything you'd know there are many more interesting parties in the story whose motives are unknown including Maesters, Ironborn, Banks, Sparrows, Stonemen, Harpies, Crones, Dornish, Faceless Men, Elephants, Tigers, Mercs, False Dragons and Hot Pie who you have seemed to disregard.
