So the professor doesn't contact his wife for over a month?

I guess you could say it's a theme he cares more about science than his wife, which seems evident by his reaction to the half robot/half human child. But still, he doesn't even think about his wife for over a month? In essence not a bad movie but I think the major flaw is that we have to believe she's there for so long and nobody except that one technician even remotely tries to contact her.
