I am interested in finding out just how the Dr. becomes a tourist to the ISS in the first place. Secondly, why that professional field? They would have so much more to work with if they had made made him a Trauma Surgeon. Could you imagine an appendix surgery in space? His sterile field would be a nightmare of hysterics. Just pulling a scalpel out of the air would have us laughing. What is he going to treat in space? A UTI? I am only questioning the story.
I am excited to watch Lee Min Ho, whatever the excuse is, up in space, as he is a good actor and will bring a fantastic show to us.
