I hate when movie center around professional filmmaking or acting, to the point I won't watch. No matter the geographical location, LA is legit beautiful and warm, I am timid about movies and tv where the plot is about making movies or tv. Some exceptions for sure, but it kills the verisimilitude. On top of that, it seems like a cheap way to stage a scene because they have all the equipment set up already, so it seems low effort. They even shot the Kraft service table! That line was definitely only for those who know they cater sets.

Mostly importantly, the killer is when it seems self-serving in a way that over glorifies the art of film-making to the point it feel pretentious. This is what makes me turn it off than any other reason. Pretentious tv/movies is a pet peeve - cooking shows so it too. I'm surprised OP is getting downvote this much.
