I'm seeing a lot of reviews talking about how boring Collective is, but I couldn't disagree more (to each their own!). I'll admit I found one or two of the specifics hard to follow - there was a clear expectation of some working knowledge of the state of the Romanian government and its political parties - but watching the events unfold altogether was riveting. The idea of "uncorrupting" a government is so easy to talk about, but it's quite a different beast when you actually have to try and make it happen.
Anthony Hopkins and Olivia Colman are - I'm gonna say it - transcendent. Probably the best I've ever seen dementia portrayed in a film. The direction and production design are of the highest order as well. Not sure what else to say - this movie is spectacular.
EDIT: Oh and the -ahem- editing, of course.
