I don't think it's quite Hollywood ending, but I would imagine it solved the quandary of "What if Hollywood demands Repo 2?" Not that I've ever been in the boardrooms generating ideas, but it would explain a fair amount of sequels that were churned out. Hero didn't get heroine, heroine didn't grasp obvious destiny and improve the world, no Disney ending for a potential sequel..
I'd have loved some more deception, but preferably from someone besides Grave Robber. I know he was the fool in any classic Shakespeare work, carrying out the work of narrator. That doesn't mean I got tired of seeing pop up every 5 minutes. We got to hear about Dad's job; I'd have loved to see the job qualifications to get that job. It's a job that could easily slide towards truly illegal activity, possibly connected to more then just 'saving' someone's life.
