In 1980, when I saw TESB in the theater at age 17, my first reaction to Vader's line "I am your father" was one of major disappointment. I feltit sounded to much like something out of a soap opera (like Dallas at the time). These kind of reveals or cliffhangers are common in soap opera's and Star Wars was starting to look like one. Well, in ROTJ it got even worse when we learned that Leia, Luke's love interest in TESB, was in fact his sister!
