Action Movie FX - Great For Igniting Our Writing?

It's an app that's been out for a while but we think it would be a great way for us to ignite our writing. Some of the clips would either be incredibly dangerous or expensive to do in real life, and we're sure Mr Lietze wouldn't want our school field ripped up by a giant robot, so luckily with clever effects on a simple app, we can create cool and exciting scenes that would start our writing off perfectly!
