Star Trek IV: The Voyage Home (1986)

It may not work well as the conclusion to the storyline of TWOK & TSFS -- and the whole "sound travelling through space" thing may really bug me -- but I just can't find it in me to dislike this movie.

8/10

Ok, how about this: the Gay Probe isn't sending sound through space because sound wouldn't affect all ship systems like it does. It's an energy pulse that travels through space that can disable ships, but once it hit's earth's oceans is creates vibrations to make a sound like certain mammals.
