To catch up Avengers: Infinity War. One of MCU movies.
When Dr. Jane Foster gets cursed with a powerful entity known as the Aether, Thor is heralded of the cosmic event known as the Convergence and the genocidal Dark Elves.
Loki agaaaaain! He’s a big trouble as always he is. Check out if he dies in this or not. You can enjoy this movie without any knowledge of Thor or MCU however of course I recommend to study at least a bit before this. Because I think Thor series are important to understand about Infinity Stones. Also some stones come and go to different MCU movies. The bed is to watch all of them from the first one to following the order. Bye bye Loki see you in other movies? Maybe. Maybe not.
