Dvolver- Don't like it

Okay, that's a bit harsh, but Dvolver is unfortunately not a tool that I'll be using with elementary students any time soon. Dvolver is a free movie maker where users get to choose their setting, characters, background music and dialog. Sounds great, but the setting descriptions are a little PG-13, the characters are racy (I would even think twice about using it with high schoolers), and dialog is limited to 3 lines of text per character, 100 characters per line. I think it would be useful for quick videos to demonstrate a point, because you'll definitely keep the kids' attention, but having elementary school students use it would raise many questions.
