I'll review your script as I have read it:
1) Your formatting is off by a mile, the first lines on the first page (after title page) are almost halfway down and everything is centered.
2) Dialogue problems. When Dilonn is talking to Amy he "SHOVES HER" and then continues talking, when there's a break in dialogue, or an action, add either (SHOVES HER) and the next line. Or break it apart and continue the dialogue with DILONN (cont'd).
3) All of the action is CAPITALIZED which makes it quite unreadable. Action and dialogue should be written the same way, using normal lettering and wording, not using a CAPS on every word, only use CAPS if it's an action, for example: Dilonn WAVES his hand, just using that as an example of course.
4) SCENE underlined. Never have this, if it's a new scene just add EXT. YARD or INT. HALLWAY rather than what you have down, this is a frequent in this script and it's rather annoying.
5) PAGE 3: Your "BOBBY (Mutters)" is off a little. The bracket part is supposed to be over the dialogue part.
6) SARAH'S introduction is off. Her name shouldn't be in dialogue format and have a description underneath. The description should be clear when you first see the character, not before and/or after the dialogue sequence.
7) Some of the other parts of the dialogue are awkward too. Such as on page 82 when "CHANGER" is talking. There's a (HE WHISPERS) part in line with the wording. Always make sure to break this onto the next line when writing dialogue as it helps the actor/actress reading it to get a better feel for their lines.
More dialogue errors occur when you have a character's name at the bottom of the page and continue his dialogue on the next one. If you can't get all of their dialogue onto the page, split it with (MORE) at the last possible line on the page and carry it on with NAME (cont'd) on the next.
9) CAMERA DIRECTIONS. As a relatively new writer here at simplyscripts, I found that adding in camera directions isn't necessary to your spec script. That's for when you meet with the director and the two of you work on a shooting script that can be used to direct camera angles. Never tell a director what to do in a spec-script, always leave camera angles out. You can have OFF SCREEN: Loud thud!; moments but no ANGLE ON or Camera goes up.
Characters can of course move towards camera in a spec-script. But try to leave most of the camera directions out of the spec-script as a director will not pick a script if he has to follow its direction, a director likes to be free to use the angles he wants to.
END OF REVIEW.
All in all it's not a bad script, but the formatting, dialogue issues and action capitalization is off and needs improving. A rewrite is definitely on the cards. Hope that helps.
