I don't understand this either. It just seems as if some people are totally against Luke having children of his own, but they're fine with Han and Leia having their own kids. It doesn't make any sense to me why an adopted child would make a better story for the ST or how it would fit better into the family saga which we've been following in Episodes 1 through VI . We had a Skywalker in the prequel trilogy and in the Original Trilogy. Why can't we also follow a Skywalker who is Luke's biological child in the future trilogy?
