Of course opinion over the film has changed. This has happened without almost all of them. TMP was considered a boring creative failure - now many people consider it a cerebral masterpiece. On release, TSFS was considered a better film than TWOK. Even TUC is bashed more now. Opinions change over repeat viewings. Also, many of the people commenting today aren't the same fans as back then. The players change as people get older and die. So, yes, everything changes.
On the other hand, the music is wonderful. The best of Jerry Goldsmith's TNG movie scores.
I like all 10 original Trek films. IMO, not a bad film in the lot. I'm apparently the only person on Earth who feels this way. Good for me, since I was never let down. :-)
