Gamma is a terrible program. It is absolutely not worth the money you pay for it. Every time it regenerates a presentation, it creates completely different characters, inserts random people who have nothing to do with the story, and fails to maintain any visual or narrative continuity from one slide to the next. It cannot keep the characters’ faces, clothing, or appearances consistent. Using Gamma has been a complete waste of my time and money. It is an awful program, and I would not recommend it to anyone.
