This consists of interviews with the casts and crews(it is in part Kevin Feige's D23 introduction to the Marvel Studios shows, which is what what this is about), all of whom have something compelling to add within their area of expertise(and there is a very clear love of what they're working on), clips from the subjects, behind-the-scenes footage, and incomplete effects shots. It's 12 and a half minutes long. This is found on Disney+, and ultimately does basically boil down to an ad for the streaming service, complete with a little love fest and playing it safe. With that said, it's very good. It spoils a lot of the MCU(up to and including Endgame), and so will this review, so that I can go into more detail. They briefly go through the character arcs of a few of the leads. They talk about character development, spending time with them between fights. Surprises. The fun they can have and all the creative freedom within, for example, Loki(the series). How happy they(including and especially Hayley Atwell herself) are to keep bringing back Peggy Carter. Getting more Ronin. Being able to add more diversity through Kamala Khan. I recommend this to any fan of the Marvel Cinematic Universe. 8/10
