The plots of this type of movie are bad if you think about it ...
If you have someone in your life, and they die,
and then you try to bring them back in some way,
doesn't that mean you are just thinking about yourself?
Especially if you do not really know how to do it perfectly.
You bring them back and they are mentally defective ... then what.
Or you clone them and they are different, or maybe not, how would you know,
or how would they know.
What are people to each other ... just replaceable things, or what?
