I wonder why I (and others, I think) find that so much less annoying when Steiner does it than when James Horner constantly reuses his own stuff. Perhaps it's because Steiner only recycled within the same series, rather than using the same motifs and set pieces in unrelated movies.
Yes. When Star Trek III sounds like Star Trek II that's cool. It's continuing a series. When Aliens sounds like Star Trek II that's less cool.
I'll be interested to hear what you think of season 3. I may have to make an effort to explore it more. Because right now almost all of my "revisits" are 1 and 2.
