The Star Trek: The Original 4-Movie Collection is a solid enough of a set and does have respectable 4K video along with the audio which is likely the same from past Blu-ray releases, even so still high quality.
Star Trek II: The Wrath of Khan is not only the best film among the Trek franchise but one of the best science fiction movies below The Empire Strikes Back. The performances are all great but Ricardo Montalban easily steals the show. This new release finally includes The Director’s Cut which should’ve been with the original collection.
“Star Trek”: The Original Series is a cheap option for those non-Trekkies to get a few solid episodes from the three seasons the show aired. Of course, if you are a fan, you already have all of these, even in high-definition for the Blu-ray releases, you get nothing out of this “best of” collection.
