Planning- choosing an idea

We decided to choose the idea that was a thriller because we thought i would be easy to target it towards our chosen audience, because the target audience is 15 we thought that we would find it easier considering that we are around the same age as our target audience. We also thought that thriller would be the easiest to achieve and the it would be easier to include the conventions of the genre. we also like the idea of the film a lot more than the others and thought that it would be a lot more exciting to film and more interesting for people to watch.
