Imagine a world where(spoiler alert you shouldn't it's already there) your vision is limited by yourself and a light technician gives a different point of view that you like, a punk pioneer in your team that is the computer graphics chief animator that gives life to your animatronics(jurassic park, and still unmatched today, cgi looks so fake and cheap). And yes you should spend a lot of time, not necessarily money, because art is time and something you have spent zero time in it its valued zero money
