Marvel has done an extremely effective job over the past few years of grounding its movie universe in a recognizable reality. Tony Stark is an eccentric billionaire seemingly pulled from the latest headlines; There’s an inescapable comic book feel baked into him at the conceptual level, and while that has the potential to turn off new fans it also makes Thor a sort of bellwether character: if audiences can get behind Chris Hemsworth and a flying hammer, Marvel’s formula is right on target. In that regard Thor: The Dark World is a direct hit, an exercise in diligent execution that delivers exactly what fans of the first film will be looking for — though not much more.
