How do you have to look at psycho pass?

I thought about going to see Psycho pass but there's actually sending "share" z. B on netflix there's psycho pass2 there's also psycho pass1? And if so, in what order do I have to look at Psycho pass?

Psycho Pass 1 certainly means the first season. Start with the first, then logically the 2. And then the film (since it takes place after the events of season 2). Season 3 is supposed to be bad by the way, so you only need 1-2 seasons and watch the film.
