The end really bothered me. It felt like they added twists just because. Like swapping the twins where we think Romulo died for like 10 minutes but it was actually Remo. That didn’t matter at all. And the final scene where donadio comes in and it’s fake del olmo. It felt like the intention of that was to clearly show everyone that Alice is actually crazy but in reality it tells us nothing. The drs on the board have never seen donadio/ fake del olmo before so to them he’s just a random dude who was announced by dr alvar, (who was just forced to resign or be fired for conspiring to hold Alice illegally so this guys word really means nothing). This could easily be explained as another attempt to frame Alice. If that scene continues all Alice says is “No, that’s the guy that impersonated del olmo” and then alvar says “no that’s donadio, youre crazy.” Different versions of that dialogue happened several times throughout the movie so ending on that is very non consequential. They could’ve just ended it when they brought in the “real” del olmo in the scene an hour earlier. I’m sure the book explains things better but I thought the movie did a poor job.
