Agreed with the bold. Thor's classic rogues are awesome. Ulik, Enchantress and Executioner, Mangog, Wrecking Crew, Karnilla, the list goes on; plus villains from Norse mythology (Surtur, Midgard Serpent, Hela, etc) and villains that started in the pages of Thor and moved on to be general Marvel baddies (Absorbing Man, Grey Gargoyle, Ego, etc). Great rogues gallery!
I would love to see at least a few more of them on the big screen, even if they aren't main villains.
BTW, speaking of Mangog, am I the only who likes to think of him when Thor flies through the Jotun Beast in the first film? Obviously not the same character, but I always felt like the design was a bit of a call back:
Anyone else see it?
