There isn't enough content that tailors to my interests. In fact, there's barely any.
Nearly every film I watch, I question the director's choices. I'd do casting and set dec differently. I'd change the music and design.
The plot and writing and character development are the things that can irk me the most.
Very seldom do I finish an experience and feel sated. When it happens, I feel elated and the experience sits with me for days. But that's not frequent enough.
We all deserve more, not less.
