The 2017 movie Colossal was marketed to be a fun film with monsters and supernatural powers. Right from the music to the dialogues picked in the trailer read "funny monster movie".
Here's the trailer - Colossal Trailer
However the film was far from being a "funny monster movie". It had some deep themes like alcoholism and bad influences/relationships. Everyone who went thinking it was a monster movie had to reconfigure their expectations as they sat and watched the film. Only a few succeeded doing that.. everyone else came out saying it was an odd monster movie where nothing was clear.
Any idea why this misdirection? Had the trailer mimicked the core themes of the movie (eg: Enemy or any Lynch film) the film could have done far better? It was an amazing movie i thought?
