Dear wise alias,

I'm considering enrolling in a screenwriting class and would like to get some feedbacks on the following instructors and workshops:

Corey Mandell: professional screenwriting and television writing workshop (so far the reviews are impressive);
Pilar Alessandra: Writing the first draft;
Glenn Benest: This workshop is conducted from his home and has garnered some pretty impressive reviews from students.

I'll finish by saying that I'm a novice having only written one spec so far w/no prior film/screenwriting background. This was before grad school and I'm now much more committed to pursuing this on a professional level.

Looking forward to your feedbacks.

Thanks!
