I absolutely loved Quantum Leap as a kid. I used to watch it every weekend, it wasn't like other Sci Fi I used to watch because at the heart of every episode was some sort of moral questions. Although the answers were not always black and white. It never felt like it was moralising at the viewer.
I loved the final semi religious reveal (a lot of people didn't), but for me it fitted into the themes and narratives of each episode.
The trailer seems all flash and style, I just hope there is some substance. This trailer doesn't blow me away but I'll watch it. If it isn't to my taste I will probably go and re-watch the original.
