If you want to talk about franchise money grabs, look no further than the Trailer Collections release. This title collected all the "next episode" previews for all three original TV series, a few promotional clips for the third TV series, and trailers for all the films up to 1995. I managed to score the laserdisc for my collection just to witness the pure avarice at work.
