Read the script from cover to cover and I liked it. It was tough, gritty and a good story, in my opinion. I found the characters believable, Hendrix-evil, Jul and Frank-sympathetic, etc. The pace kept moving and didn't get bogged down. I did have a few points to consider when you revise it.
-The language (F-bombs) and violence (death by ax), while realistic, will probably get you an R-rating. This will limit your audience to some degree. If you are not worried about that, then ignore this point.
-There were numerous typos and misspellings throughout the script. I had to reread a couple of portions to make sure I understood. Also, the use of Fade out:/Fade in: was not something I had seen in the body of a script before.
-Long on description at times. Much of the action should be pared down and made more concise.
-Continuity: when Frank and Jul break into Hendrix's house, the way that Frank "McGyvered" the alarm system seems forced and glossed over. How did he do it as an ex-cop? What gave him that skill?
- Finally, some of the action seems cliche, i.e., when Rebecca shoots Hendrix. Numerous family members are current or prior law enforcement. While I was not, but military, it seems highly unlikely that the officers would have let her wonder around, much less acquire a firearm. After she shoots, they rush to help Frank and secure Hendrix, but nobody tries to disarm Rebecca. Since Hendrix survived only to die in interrogation, I believe you could delete the part about Rebecca shooting him without losing anything to your story. Or you could have her kick him in the balls or something as a payback for holding her against her will.
Anyway, I enjoyed the read. Hope you continue to refine and polish it.
Best of luck.
