Gnarly Vines has follows an interesting take on cult culture, and The Father's extraterrestrial abilities emphasize how much control a leader has over their blind followers. The first ten pages would have drawn me in more if there weren't as many typos and lack of formatting. The script doesn't appear to be edited or looked over much.
The characters are somewhat one dimensional, and I am not emotionally connected to them. Because it is a cult story, it is something that most people already cannot relate to. In order to make the characters more appealing, I believe it would be appropriate to add more character building within the first couple pages. What do the characters like? What are their thoughts about The Father? What has The Father done in the past that was incredibly disturbing? The script seems to follow that the characters will be fighting against the diabolic nature of The Father and pinpointing his weaknesses.
I believe it would be interesting to reveal that the characters might be plotting against The Father, not just showing some dislike, like in Charlene's case. Since she has been under The Father's control since childhood, she could maybe have a history of escaping revealed early on. I believe that this script has great potential, but it does need to be edited and tweaked a bit more. Human interaction with another sentient species, especially in the case of a power struggle, is always fascinating, and the setting of Gnarly Vines opens the script up to an abundance of possibilities.
