This is, if you watch the MCU movies in chronological order, the seventh, after Captain America, Captain Marvel, Iron Man, Iron Man 2, The Hulk, and Thor. If you are watching them in release order, it is the sixth, after Iron Man, The Hulk, Iron Man 2, Thor, and Captain America. It is in part a sequel to both Thor and Captain America, with the Mcguffin of Captain America (the Tesseract) and the villain of Thor (Loki) being front and center in the story. Basically, Loki is tasked to use the Tesseract to open a portal through which an army of aliens called the Chitari can come through and take over Earth. The Avengers have to team up to stop him, leading to what would be referred to in the subsequent movies as "The Battle of New York" and have reverberations throughout the other movies and the tv series that the MCU would spawn.
For those who get the 4k disc, the A/V quality is excellent. I do not count myself as an A/V expert so I cannot really tell you whether the 4k UHD disc is a huge upgrade over the initial Blu-Ray release (there are certainly sites out there that can do that), but as a novice, it does look like, when watching it on a big screen 4k tv playing on a 4k Blu-Ray player, the UHD disc does look better than the Blu-Ray version. The extras include a director's commentary track on the movie, several making-of and behind-the-scenes featurettes, and a Marvel One-Shot short film starring Lizzy Caplan set after the events of the movie. As is the case with many UHD releases, the UHD disc just has the movie itself and then the regular Blu-Ray has all of the extras. I listened to the commentary track years ago when I purchased the original Blu-Ray release before everything all the allegations about Joss Whedon being a raging asshole came to light. From what I remember it is a pretty standard director's commentary, but I refuse to listen to him talk about anything, but it is there if you want to listen to it.
Overall, the movie is wonderful. I think Marvel did a good job by introducing the characters in stand-alone films first and getting the origin stories for most of them (all but Black Widow and Hawkeye) out of the way and developed (at least to an extent) before they started doing the big team-up movies. It seemed like the cast had great chemistry, and worked well together. Of course, the big casting change from the prior movies was the fact that Mark Ruffalo was brought in to play Bruce Banner/Hulk, replacing Edward Norton who seemingly wore out his welcome very quickly when filming The Incredible Hulk. Even though Ruffalo was kind of shoe-horned in, given that this was the first movie in which all of the major actors worked together, it worked out well. The movie is, as you can imagine, mostly an action movie, but does have some comedy and even drama mixed in. It also started the tradition of having both a mid-credits scene that advances the storyline (this one introducing the "big bad" of the initial phases of the MCU, and a post-credits scene that is meant to be more fun or tie back into the movie you just watched. So, if you are a fan of superhero movies, this one is definitely worth watching and pays off on the prior movies quite well.
