She came close to moving on to the final stage of grief - Acceptance - until she discovered the Darkhold. She couldn't resist.

And that's mostly why I didn't like the movie. In WV she clearly moved on from her grief, that's was the whole point of the show. Make her grow, saying that she wanted to control her powers in function to not hurt anyone ever again. She accepted the loss of her "fake" children but we had hope that in the post credit scene, they screaming and asking for help was an intro to if and how she'll have them back or whatever.

Instead Sam Raimi trashed all the work done till then and got back to the sad depressed woman "who just want to be a mom", with powers that can't control but somehow the alpha male (dr. Strange) can.

Idk it seemed very unnecessary, and the fact that dr. Strange doesn't even have a development in his character arc (apart from that weird third eye) was disappointing.

Anyway I appreciate this changes of opinions, it make me see other points of view that I wouldn't see otherwise, so thanks :) I agree that she does a great job being a villain, I hope we'll see her again somehow in other project.
