The setup for this film is exactly what I like in my science fiction. A question is asked, and the film attempts to provide those answers. In this case, the question is: what if we could bring people back from the dead? Who's in there? What are the implications thereof?
A quick note about the corporate takeover scenario in this film. I have been a part of two separate mergers where a larger company bought the one I worked for. In both cases, what they were after was the people and their knowledge about the business that was purchased. You do this because you lack a certain capability in-house and so you purchase it instead of spending years (and lost market opportunity) on your own research, pawing around in the dark so to speak. In this movie (it's not really a spoiler), the researchers are given a grant but the granting company is bought out. Company representatives then come and take their data and materials, but cut the researchers loose.
I doubt in the real world this would happen. It would be far, far more likely that they would take on these researchers (the only ones to make a monumental, earth-shattering medical discovery) and give them additional funding to continue their work. Why would they run the risk of alienating the only people who have been able to accomplish a feat that has eluded the efforts of all other medical researchers for hundreds of years? It makes no sense, and I suspect that the writers have little to no actual business experience. I know it's necessary for the plot, but each time a writer takes a super lazy, idiotic shortcut like this, a cute and harmless kitten somewhere in the world dies because it can't stand to live in such a lame world as ours.
