I don’t know why anyone’s surprised that the Russos think Thor’s at fault. The Russos gave Thor and Loki and Quill and Gamora the same relationship arcs. Both Loki and Gamora get fridged for Thanos’ character and their brother/love interest’s Manpain™. Both Quill and Thor fail to do what they’re supposed to because they’re so upset that they can’t do what needs to be done. Quill ruins everything after realizing Thanos killed the love of his life. Thor ruins everything because he wants to kill Thanos slowly, intimately, to avenge Loki and everyone else he loves.
They fridge characters for Manpain™, then condemn Quill and Thor for experiencing that pain.
What pisses me off more is that Loki and Gamora should be the ones fucking killing Thanos, or at least facilitating the formation of a strategy. They’re so wasted in this movie. So fucking wasted. Imagine having three characters (Loki, Gamora, and Nebula) who’ve spent time with the bad guy–who know the bad guy–and throwing them away/hardly using them. Why is Strange the only one with the plan?
