I was kind of lucky. I had been anticipating the release of Age of Ultron to be on 1 May 2015, but turned out that it was released on 22 April in my country. We got two tickets for the evening and so yesterday I watched Age of Ultron :)
Avengers: Age of Ultron opens with a fight scene between the Avengers and the Hydra soldiers led by Strucker in an eastern Europe city called Sokovia. The team succesfully beat Strucker and find his experiments there, including the Maximoff twins, Quicksilver and Scarlet Witch. They also find Loki's scepter, which they bring back to Stark's place. Without the rest of the team knowing, Stark and Banner (the Science Bros :p) use the scepter to build an artificial intelligent called Ultron, which is originally intended to be installed to Stark's peacekeeping robots seen earlier in the movie. They fail, however, then they leave the computers on while they go upstairs where a party is being held. After the party, the team gather and then this scene happens, where Ultron first comes alive and makes the memorable speech we have seen in the clips released by Marvel a few months ago. Together with Quicksilver and Scarlet Witch, Ultron tries to create a real body while also try to "save" the world. And by "save" he really means to sweep all humankinds off the Earth to start anew.
Age of Ultron serves as a good climax for Phase Two. Thanks to Scarlet Witch's ability, we can see a glimpse into the Avengers' personal deepest fears. The whole movie is personal. We get to see into Hawkeye's real identity; we get to see Black Widow's past and the reason why she seems so cold and "business-minded". Also, we get to see some romance, something that didn't occur in the first Avengers movie. I totally didn't see the romance coming, and I'm sure most of you didn't either, but it gives a little nice surprise into the mostly-dark theme.
And because of the mostly-dark theme, the Marvel jokes don't occur too often. There are only two running jokes in the movie; the first one isThor and his hammer, and the other one is Captain America's 'old man'-ness. The lack of humour is understandable, though. Ultron gives a real threat to Earth and he really seems too strong for the Avengers to beat. His origin also breaks the team and the whole Captain America versus Iron Man (which will be the main story of the third Captain America) can be seen in this movie. The Avengers are doomed. There's no joke about it.
I'd give Avengers: Age of Ultron 4,5 out of 5 stars. Totally recommended! But if you're not following Marvel Cinematic Universe, I'd suggest you watch the previous installments first. I mean, man... You really don't know what you're missing out. Haha :p
