Marvel has released the first poster for Thor: The Dark World. Honestly, I find this poster to be a little lackluster. This could just as easily be a poster for the first Thor film -- nothing about it really states that this is a sequel or continuation (sans the title). Disappointed, I am.
That is what I really like about the Sam Raimi Spider-Man films, they usually had a reflection of the film's main protagonist in Spidey's eye. As with Thor 2, not the case.
