"Just sit and write. The structure is a guideline, not a rule."
Couldn't agree more. Reading books and watching films is the main source of cinema knowledge. I've never heard of Schechter's archetypes before but that's exactly what I've been using for my feature film script. Things come naturally when you're curious and eager to learn.
Although complicated that diamond is still interesting as a summary of different ways of storytelling.

There is an image with the prices on it. 199 instead of 249 and 139 instead of 179 for single software use.

Criswell and Cinema Cartography are my favorite Youtube channels right now. Way better than most of the channels presented here according to me.

It's way too hard!!! I guess I would choose 2 high quality entertaining horror/SF (Blade Runner, The Texas Chainsaw Massacre, Alien or The Empire Strikes Back), a comedy or a film about life (Something about Mary or La Dolce Vita perhaps) and a 2 huge masterpieces from my favorite directors (Kubrick, Malick, Lynch, Weerasethakul, Tarr or Tarkovski). Because if those are the only films I'm about to watch for the rest of my life they need to be diverse and different but also rich enough so I'll always discover something new. I would focus on what I gain from them (philosophically, intellectually, spiritually) and how I feel after watching them. I would probably focus on length too. Having Satantango or Once Upon A Time In America would be a good idea.

Yes, that's the kind of questions every filmmaker wonders once. I think there is no rule. I've been writing for the past 5 years a slow film with almost no dialogue, there are now 126 scenes for 81 pages... Most scenes are short because they are slow and I don't want to write "he walks" 25 times in a row. But they are all useful to the narration (there was way much more before), so it's ok for me.

I read it with Werner Herzog's voice in my head ;-). Good read, can't wait to watch the film.
