Resembling Ghibli is always a good sign in my books. Not much can go wrong there.
I picked up something of interest from that first family conversation before. The fact that the father has quit the trading business and lived in L-something for 5 years without the mother knowing reveals that they never brought it up before. The only reason I see that it didn't happen was that they simply don't care where each other are. and that they can truly live through their doppels as if they were really there. It's a lot different from our webcams and other such things, since no matter now connected we are, we still maintain a sense of self - and a sense of "here" and "there".
