I haven't seen Wandavision because I'm not a Marvel fan, but now I want to watch it just to compare it to Nomadland, which is one of the most realistic portrayals of grief I've ever seen.

Edit: However, ironically, one of my favorite quotes on grief comes from the Nolan film Batman Begins "And one day you catch yourself wishing the person you loved had never existed, so you'd be spared your pain" Not that I've ever experienced grief that way, nor do I believe I know anyone who has, but I think it's an interesting idea.
