"Sigrid is a Mary-Sue she's way too strong and some characters are cannon fodder while others are too OP."
Maybe, just maybe, she's "way too strong" compared to the rest of the non-god characters because she obviously has experience with combat along with her husband. She FOUGHT in what's to be implied as many battles before the series even started. She's jaded and her entire family was killed, what do you expect of her?
When it came to characters being cannon fodder (referring to the old gods, humans, etc), it's because they were most likely civilians, inexperienced people, or gods who have not engaged in combat in a long time who joined the effort in killing Thor. And when you are a mortal in the face of ACTUAL GODS, of course they're going to overpower you. Do you expect them to put on a fair fight?
