No one cares about your short.
That's not what we do here, weirdo.
You're correct. The two brothers wouldn't have been used as peril-props if this were a Spielberg film.
If you wanted to take the time to find the root of all problems with Jurassic World, and I don't recommend it because it would be a total waste of time, I'd start with logic. High heels, this graphic death, cathode ray tubes, weepy mom, Vincent d'onofrio... the list goes on. Everything that is "wrong" with the film comes from lazy logic or gaps in logic. In the end it doesn't matter, people are there to see dinosaurs and it delivers dinosaurs. It'll make over a billion dollars whether or not the script has logic gaps.
I like Neill Blomkamp's films but he has essentially made the same movie four times.
Agreed. She's using a labor intensive process to illustrate the blend mode features. Blend mode is a nice tool but there are easier ways to achieve the effects she created.
CELTX is a free screenwriting application. It's an acceptable program for just getting your feet wet in an introduction to screenwriting class but if you want to go any further I'd suggest buying something more powerful. Since you're a student you are eligible for discounts on products like FinalDraft that will allow you to work like an industry professional. Good luck.
