Do Sci-Fi interfaces look reliable?

I'm designing interface for medical program, which will be used to show clients their data from sensors in real time. So, it will not be used for real work and will only implement some basic functionality. Because of that, I can sacrifice some usability, and create more visual elements, like in Sci-Fi movies. But do these interfaces look reliable for people? Do people trust them, or they look like fake from movies? All data will be 100% real, so question is only about way of demonstration. Maybe I should forget about Sci-fi elements and create regular clean design? What do you think?
