Gah, I don't think I would have liked that ending at all. The theater ending is a little too stereotypical 'feel good', but better than 'oops, accidentally murdered 5000 people, let's get to the inbreeding!' I agree that your ending idea is more interesting. Personally, my biggest complaint was the cliche of 'being revived after it looks like he wasn't revived', like, just once, how about the tech works like it's supposed to and the guy just is revived? I'll never understand why that is still considered dramatic.
