1. Thanos Finally Gets His Act Together
Despite only making two appearances in the Marvel Cinematic Universe, Thanos has so far been shown as being a pretty ineffective villain. After all, his quest to retrieve the Infinity Stones has failed again and again, so thank goodness for Avengers: Age of Ultron's mid-credits scene finally showing him preparing to do something about it. It's about time. Clearly sick of middle men like Loki and Ronan failing him, Thanos can be seen approaching the empty Infinity Gauntlet and talking about finally retrieving the stones himself. The fact that The Vision is walking around with The Mind Stone on his head will more than likely be what brings the Mad Titan to Earth in the sure to be epic two-part Infinity War movie.
