Better than the first two installments, but still garbage

The Thor franchise should be the worst in Marvel Cinematic Universe. The first two installments are complete garbage. This third episode is improved, but in a very limited way. More concretely, the screenplay is added with more adventure and humor, but the plot as a whole is too scattered and unfocused. Particularly, the gladiator part is unnecessarily too long. The talent of Cate Blanchett is largely wasted in such a movie. I hope that she could play some more challenging roles.
