These three episodes are a little on the weak side, in my opinion. The first "The Different Ones," for me, was just warmed-over Twilight Zone. A young man who lives in an "advanced" culture has the great misfortune to be born deformed. He is hideous to the eyes of everyone and his father, who feels greatly for his misfortune, doesn't know what to do. One of the options for people born this way is termination. They have, for whatever, reason, developed an exchange program with another planet. The wind up...and the pitch.
"Tell David..." is an odd episode. A woman loses her way, trying to find her house, and ends up getting help from some odd people. They have technology beyond that which she is used to. David, the young man (who has the same name as her little boy) is a master at repairing devices she's never seen. When she returns to her husband, he is dressed as a monster and nags at her and chases her. It is obvious that this is the way he sees her. She is monumentally jealous. She comes to realize that she has an opportunity to change her history, to prevent herself from doing a deadly thing. As it goes along, it becomes nonsensical. It also gets caught in the problems with the mutation of time.
"Lagoda's Heads" concerns a couple of men who visit a medicine man in an African jungle. The brother of one of them has disappeared and it is suspected that Lagoda, the medicine man, is responsible. Lagoda does things with shrunken heads that he talks to. He also can put curses on people. A young woman who is cursed, tells the man his brother has been there. Through a series of spells and counter-spells involving the young woman, everything comes to a "head." Or I guess it's heads. Terrible acting and another convoluted plot.
