Black Mirror "Be Right Back"

Martha and Ash had both just moved into their new place when Ash suddenly passed away. Martha's friend Naomi signs her up for this site in which she gives it Ash's online information. Once it has his information the site is able to "talk" to Martha as if it were the original Ash. At first she is only able to email him then she can speak with him through the phone and finally she is able to bring him to life through a robot. The thing with this new Ash is that he is only as much of Ash(1) as what there is of Ash(1) left behind, such as how he expressed himself through social media, videos of him, and memories that Martha has. Because Ash(2) is constantly learning new things about Ash(1) he is sort of like a child in the sense that he is learning what responses are appropriate. Ash(2) is also dependent of the of Martha who is the person who brought him to life. I think in a way Ash(2) could learn enough to the point that he is almost identical to Ash(1) but at the same I don't think that it would be enough. He doesn't age, sleep, eat, get sick, have random moments in personality like a person would. If anything Ash(2) would at best be a whole other person with new and different experiences. So there is no knowing if the way that Ash(2) responds to these new experiences is the same way that Ash(1) would have responded if he were still alive. So at this point Ash(2) could react as a whole different person or stay at the same place personality wise because that is where Ash(1) last left of. Another issue is if Martha ever truly recovered because I think at first she defiantly saw this as an opportunity to help her grieve but we don't know if she the end of her grieving process. Or maybe she did and that why she put him in the attic. Just like someone who initially clings onto items  and memories of a loved one who just passed away but they eventually starts letting go. They visit the items and the memories less and less until those things are put away only to be visited on few occasions. I think towards the end she realized that Ash(2) can't ever be Ash(1) and I do think that she did get over it at least in the way that most people do. I don't think that this method of grieving would work for everyone but at the same time most things don't work the same for everyone.
