What more can be said about Star Trek 4 than that which has already been mentioned by countless beaming (no pun intended) reviews over the past 15 years. It is a classic melding of Science Fiction and comedy, amusing without resorting to insulting spoofs and remaining respectful towards the spirit of the original series.
Perhaps usually remembered simply as "The one with the whales" it details the fugitive crew of the USS Enterprises voyage back through time to rescue two humpback whales (long extinct in the 23rd century) which may hold the key to mankinds salvation. Replete with good-hearted ecology messages and bursting with 80's period flavour it tells its story without drifting into preachy morals or sickly sweet nostalgia.
The presentation here is almost uniformly superb, the range of extras available (from full length commentary by Shatner and Nimoy to over 6 hours of behind the scenes retrospectives) is in keeping with earlier releases in Paramounts revisitations of the Trek movies and as such proves utterly fascinating and informative, menus are fully animated, sound quality is strong throughout and the selection of subtitles available is astounding.
Only one aspect brings a slight quibble, picture quality is acceptable, the movie certainly looks as good as any home cinema release so far, but it lacks the remasterinbg afforded to the Wrath of Khan release. A few scenes feel slightly grainy and there is a loss of colour depth on occasion. Minor problems however in such a commendable and well-priced package.
Not only one of the best trek-discs out there, but one of the best DVD's in general. Bravo Paramount!
The only real negative is that its Star Trek 5 next...God help us all!
