It’s not actually that great a movie is it? Iconic, yes, enjoyable for sure, but from a cinematography point of view the acting is crap, the script is simplistic, the filming is average at best. All IMO of course.
Perhaps it wasn’t your cup of tea, but I thought it was excellent, as did more other people than not. If you read any review of it, it gets 90% (RT), 8.2/10 (IMDb) , CinemaScore gave it A-, the list goes on. The film has received literally dozens of awards and accolades.
