This is what it's all been leading to.

The Marvel Cinematic Universe has changed cinema. Since Iron Man in 2008, Marvel have been constantly adding to this universe, slowly building up to the biggest cinematic crossover of all time.
Everyone is in this. The Avengers, the Guardians of the Galaxy, and some other characters (Spider-Man, Doctor Strange, Wong, etc.) This itself is a huge feat, and the fact that Infinity War is as good as it is is a testament to the Russo's skills.
The story is that a Titan called Thanos wants to collect all six Infinity Stones, each containing a power. When he collects all six, he can snap his fingers and wipe out half of all life in the universe. The Avengers find out about this, and set out to stop him.
The big twist is that they fail. For the first time in a superhero movie, the heroes lose, and the villain wins. He gets the stones and kills 50% of the universe, including a lot of the main characters, like Spider-Man and Black Panther. This is impressive, because you go into these movies expecting a couple of hours of action, then a nice resolution at the end. The way The Decimation is filmed is great too; there's no music for the entire scene, and the camera lingers on all these beloved heroes fading away. It's beautiful and depressing, and if you don't know the Marvel schedule (Spider-Man, Black Panther, and the Guardians all have movies coming out in the next few years) it's traumatic.
Everything else about Infinity War is great too. The visuals have really improved, only a couple of years ago was there some controversy over the fact that many Marvel films look "dull" and "bland", but this movie is beautiful. It's so colourful in the action sequences, so dark in the Decimation scene, the use of colour really adds to the movie in a big way.
Another common complaint about the MCU has been that there's no memorable music, but Infinity War once again fixes this issue by having a genuinely great soundtrack, topped off perfectly with the Avengers main theme.
The writing, acting, and fight sequences are all great too, which I've come to expect for these movies, but seeing all these characters together in the same film is amazing, and probably the biggest draw card.
Overall, Infinity War is incredible. My favourite movie of 2018, my favourite MCU movie, and possibly my favourite movie of all time. Go see it.
