Did Wise talk about his attitude towards special effects? His earlier film The Day The Earth Stood Still is a classic even with homespun special effects. Perhaps he thought the story telling was more important.
Star Trek V is a turkey, so the 4 film set is probably good enough for the general audience.

Edit As a lukewarm ST viewer, the UK import blu-ray for 10 films for $34US satisfies my needs. See notice of sale price a few years back here...
