Two down, three to go. Phase Two of the Marvel Cinematic Universe officially kicked off mere months ago with Iron Man 3, and now here we are again. This time, it's Earth's Mightiest Avenger that's making his thunderous return to cinema screens. Although its title may have you thinking that this sequel takes the The Empire Strikes Back route of being darker in tone -- Thor: The Dark World is a rousing and fun entry in the canon that is Marvel's Cinematic Universe. It has an energy and a momentum that keeps it deliriously entertaining through and through -- and, like any good Marvel film, it deepens the lore of the franchise, leaving audiences anxious to find out where the next film will take them.
