Why is it that the best warp drive effect happens to be in a 40-year-old movie, TMP? It really, really conveyed the feeling of going abnormally fast with that rainbow-flaring-flash effect and the Enterprise "tracer" being so detailed. Then in Star Trek II, the warp drive effect was similar but more modest. Then with each movie the warp-drive visual effect kept getting lazier and lazier, like they didn't care. Although First Contact has a fair warp jump near the beginning leading up to the Borg battle (but nothing like TMP's).
