2. Flashbacks, Part 1

Thor 2 (opening scene), Thor (opening scene)

Okay, before we get to the first actual movie, we have some business to take care of. Our timeline starts in the distant past, deep in the before time. So far back that it's somewhere around 3000 BC or so, if my math is right.

So start by watching the first scene of Thor: The Dark World. Here, you'll watch Bor fight against Malekith and the Dark Elves during the Convergence. It's a weird beginning to your long viewing odyssey, but it’s a logical one. We get good and evil, we get an Infinity Stone (which we won't see heads or tails of for a decade of hours), and we're immediately introduced to all the Norse stuff.

Next, watch the opening scene of the first Thor movie. Here, we get Odin fighting Laufey, and we get the adoption of Loki. It's funny that we meet our first villain before our first hero. We also get that kid Thor and Loki scene to start establishing stuff.

But now it's time to skip ahead.
