The story was an utter failure. I was sleeping for the first half of the movie.
-If the Thanos, has the time stone, why did he not foresee all possible outcomes before destroying the stones.?
-Thor singlehandedly "killed" Thanos in infinity war when he had all the stones. Thor, CPT-America and Ironman could not match him in combat when he had no stones. WTF?
-Stones emit gamma rays? WHAT?
-Taking the stones from the past would change the future events. What would happen to Ragnarok then if the Loki has no stones to take?
Boring and lack of story telling
