Re: Thor Sequel Ideas
It's a little difficult to say because we don't really know where things will stand after the Avengers but I'd like to see the sequel be back on earth, maybe with hints of other tensions building across the other realms. The third movie could be the massive world-shattering battle between Asgard and her enemies.
For Thor 2, I'd go with Amora and Skurge as some of the bad guys. The Enchantress' plan would be to eliminate Jane Foster as Thor's love interest. This could involve any number of things but primarily, I would love to see her empower the Wrecking Crew to do her dirty deeds on earth.
It would leave the opportunity to spend time in Asgard and on earth.
