Just to point out, different writers often have different approaches to the material. I know both Lee and Simonson have written Odin in the past as having respect for the power of Hela. While he may be the All-Father, Hela is the goddess of death, after all.
Speaking of which, my assumption is it's her razing of Asgard, and collection of the souls lost there, that empowers her to the point of being able to break Thor's hammer. Somewhat along the lines of a callback to the scene from the Avengers where Thor's lightning super-charges Iron Man's armor enough to allow IM to go toe-to-toe with him for a brief time. If that is the case, I'd personally say the utter destruction of Asgard and the majority of its' inhabitants more than justifies a special case of her being able to crush the hammer. YMMV I guess.
Honestly, I can understand and empathize with this sentiment. I loved the DnA version of the team, but dropped the book fast after the BMB soft reboot relaunch of the title because I hated what he did with the characters. I find Gunn's MCU version a frustrating, but still ultimately entertaining and enjoyable, middle ground.I completely ignore GotG galaxy cause that movie was very clear that they did not care to follow anything of the comics with the movie. Other movies have tried to take some stories and brought them to screen even they change stuff around but Guardians is just a straight up use of the characters and setting and nothing else.
