Is this movie being a flop a consequence of the decline of film journalism?
Until a couple of decades ago, this was the kind of movie that general audiences avoided, but critics used to love and praise. They weren't hits, but they paid the bills.
Right now, The Lighthouse looks like a sure flop.
Before the decline of modern journalism, you knew that critics used to love artistic movies and (often) despise pop-corn ones. A good rule of thumb was to trust them with the first ones, and check word of mouth with the second ones. And that worked quite well.
Fast-forward to modern day. You check RT right now, and while critics praise 'The Lighthouse'... they place it about the same level than 'Brittany runs a Marathon' and 'Hustlers'. WTF? Then you go down the list (critics' score) and you find Joker and Fast & Furious Hobbs & Shawn sharing a similar score. WTF? (again). Then you go top of the list, and you have 'One Piece the Movie' as the best movie in movie theaters. And don't get me wrong, I love Anime, and One Piece is good fun, like Fairy Tail with pirates, but, top critic score?? WTF? (again).
Years ago, you knew that critics used to despise pop-corn movies and love auteur films... so you had to make adjustments based on that. Once you adjusted, though, critiques were quite trustworthy. Right now, critiques feel like a joke.
Traditionally, The Lighthouse was the kind of movie that should have been pushed forward by critics. Not to the point of being a hit, but having the bills paid. Sadly, when critics are not trustworthy anymore, movies like this one are the ones that have the most to lose.
