Large-budget movies start to lose focus on the story and the actors, and it becomes purely about the visual, or CGI, or framing with the cranes, or whatever it may be.
I was very, very young when I first started acting. My first movie role I was in, I was eight years old at the time. My mom got me involved in community theater stuff when I was like five or six years old. How I learned to read was by reading the captions on TV, and I grew up from a really young age watching tons of movies and television.
TV is longer form, and that's sometimes a positive, and sometimes a more challenging thing. As an actor, you want to be able to have your character develop or transform in some way. When you're acting on a show over the course of multiple seasons, you get to watch a character really grow and change, and go from one place to an entirely other place.
