A Sure Sign The Novelty Has Worn Off
FTR, I was too young for my parents to let me watch the TV series on its initial run back in the Seventies. And since I've never had cable, and it wasn't broadly syndicated, I've never actually seen it. So I never cared to see the movie, if I had ever found it on DVD.
Starship Troopers had an in-name-only sequel. Then again, I've always considered that franchise an in-name-only adaptation which missed some of the main points of the novel version.
