Avengers: Infinity War

Loki is killed by Thanos and Thor dies under his hands as well. Thanos already has 3 of the 6 stones and goes around getting the rest in the name of sacrifice for peace by exterminating worlds. He killed his daughter Gamora from Guardians of the Galaxy for the Gold soul stone. To get this stone he had to sacrifice the one he loves which he did it without much hesitation, just some tears. Next he took the green Time one from Dr Strange. Finally he wields the last yellow Mind one from Vision while fighting Black Panther and his army in Wankanda. Thor is revived and rescued by Guardians. Fox, Groot and Thor get his hammer done, while Gomora's bf, muscle man and slug lady fight it out after joining forces with Dr Strange, Ironman, Spiderman against Thanos. 

Well Thanos crushes all of them, wipes out 50% of Earth including Black Panther, Black Window, Scarlet Witch, Agent of Shield head...

Depressing.
