I don't disagree with any of the opinions against the film. But, I enjoyed it for a specific reason.
It suspended my disbelief.
Sure, compared to real life and the likelihoods of political reality in the UK or the USA, it is a bit far-fetched. But, it's exactly what I figured it would be. I enjoyed the casting, cinematography and understood the director's intent behind several different choices; despite the fact I had directed it differently inside of my mind.
It was also the director's first feature-film debut, so there's that. I also blame Amazon for, likely, under-budgeting the film.
I'm curious how it might have been different if another studio out-bid Amazon for the film rights. A studio with more of a history standing behind itself.
Also, Greg Berlanti produced — and he was behind Love, Simon and Love, Victor — so I think that contributed partially to some of the tropes people grow tired of. But alas, rom-coms will always rom-com.
