It's actually much harder to watch Oppenheimer, because you have to see him say his famous catchphrase in a scene that could show John Green how to make sex more awkward
My gf and me watched both Oppenheimer and Barbie a few weeks before we got together. I loved both movies equally and my gf definitely preferred Oppenheimer.
I would watch Barbie 500x before I watch Oppenheimer again. That movie was made for people with 10 second attention spans and that cinematographer should be arrested. Im surprised people didnt get epilepsy watching Oppenheimer.
You can watch The Barbie Movie alone as a single man but you'll be the only single man in a room filled with couples and girl groups.
I know because I was that guy.
