This movie is no good.
Thor is not a good character and the antagonist of this movie is also flat.
The story is good where there is loki in the movie. Character loki is so likable in this movie.
Loki's feelings about her mother and his inner demons is well portraid in this movie. Feels like a loki movie.
Thor is almost flat in thia movie. The portals are just for sake of plot they do not add anything to the story or the experiment they are doing.
The eather stone was too flat. Like a space stone we really don't understand its powers.
Loki did everything that thor must have done it. So as I said it seems like a Loki movie.
