I'm surprised they call out the Conclave as an example of a good movie. It's not a bad movie, but the final twist (I'm not going to spoil it) is way over the top and almost absurdly Hollywood.
It wasn't just the ending. Any time a priest casually breaks the seal of the confessional and nobody bats an eye, it creates this weird surreal effect where you can't even tell if the author is aware of what he's doing.
