Re Shoot?

I'm debating whether or not to re-shoot a different idea, I feel that this idea is a bit stale and my project would benefit much more from a different idea being explored. It could either bring a better outcome from the second shoot or make me feel more strongly about my original idea. I also feel if I don't shoot another idea I may look into making the film more sinister and giving it a twist like the opening sequence of Dexter, which I looked at for my research. I may also be wrong as I know that with design sometimes you get bored of your work if you have been looking at it for a prolonged period of time, especially with video editing and the short space of time having to be filled.
