Spoiler He did murder a god (his god) right when his kid died and he got the sword, but I hear you - why not show him and Lady Sif battling where he chops off her arm and kills the giant god. That would have made sense. Valkyrie is a tough character, she's been taken in several different directions, but in the end, she's a third or even fourth fiddle in these movies and lacks the time to really develop. She is RIPE for a TV show, that's where she would absolutely shine. Sadly I don't think one is in the works.
