We all remember this… Just going to plop this down for everybody to think about, but I think we have already seen the “new” planet where Thor and Hulk are going.
The Kree Monolith was a gateway to a planet. Which planet? Hmmm… Perhaps Kree? More than likely. We’ve had a few Kree connections in “Guardians of the Galaxy” and “Agents of S.H.I.E.L.D.”. Ragnarok is, traditionally, a tale of the end of the world, in which (Thousand plus year old Spoiler) Thor dies.
I am pretty positive that this won’t be a “Planet Hulk”, but it should be a buddy flick, full of fun, laughs and incredible battles. Oh, also, I don’t think that they will actually kill off the Son of Odin but there will probably be a huge change in his world.
