Which actor is worse in this? Affleck or McAdams?

IMO:

Affleck was vey bad (especially the part where he's arguing with the Point Corp CEO...over acting would be an understatement),

But McAdams was much worse. There was some part in the movie where Crowe tells her they're off the story and she replies "Ohhh nooooooo".

It is truly cringeworthy. It is awful. Everytime I think about it I shake my head and try to push it out of my mind. I'm contemplating therapy.
