Many, many questions about this movie
1. Only one-two pods wake up out of 5,000?
2. There is only one auto-doc for 5,000 people?
3. Auto-doc can conveniently put someone into hibernation, but regular pods can't be programmed to do so again?
4. They couldn't build another auto-doc with the spare parts?
5. The crew of this ship must be hundreds of years old if they are making this journey over and over again. So by the time this ship goes back to Earth, they will have been gone 240 years. That would mean that when they return, their skills would be massively outdated or obsolete and the world would have changed completely. Their families would be long gone. Why would anyone do this job, unless it was a one-way trip?
6. Seriously, no kids after a lifetime on the ship? There would be at least 50 running around, if you consider that incest would be going on.
7. How would this colony produce food after reaching the planet to sustain itself?
8. Are we sure they're both really dead? It is entirely possible one died and the other could have gone into the Auto-Doc early. If there's a sequel, I assume this will happen.
