It was less odd, yes, because there was no good reason for only women to show up to help each other. It just wasn't "realistic" within the confines of the story. I'm all for more powerful women in movies, but that scene did nothing for me (but I get how it would for others, especially girls wanting strong role models) The whole final battle was full of stupid, imo, and fan service. Blech. I really think I'd have liked that movie a lot more with a better final battle. As for compared to fighting Thanos, several others did fight him, it just so happens those three are the stars of the show.....but ya, why not everyone team up on Thanos at once? All that power, and Thanos can stand up to the Scarlet Witch, a God, Iron Man and his tech? Or Captain Marvel? No chance, not w/o the stones. Why didn't Thanos have his guards with him? Why the arrogance?
