In short, this film gets everything right. Music, acting, effects and pacing/editing.

It is well written and has the usual cheesy moments we would hope for from the originals series but also serious moments and even exciting action moments.

The ending sequence literally had me at the edge of my chair which is quite impressive for a 1991 film being watched in 2017. It is hard for me to pick the best original series film but this will definitely be among the list. Along with Wrath of Khan and Search for Spock. But each are great in their own way.

It kind of brought tears to my eyes in the end because you can tell the staff were very emotional about this being their last time to be in Star Trek and that emotion definitely came through on screen.

Also I have to mention, a big shout out to Christopher Plummer for his stellar performance in this film. It just would not have been the same without him!

Having been one of the shows that was part of my childhood and growing up, the original 'Star Trek' still holds up as great and ground-breaking, even if not perfect.

The last of the six 'Star Trek' films based off the original series, 'The Undiscovered Country' is also one of the best of the six. Along with 'The Wrath of Khan' (the best) and 'The Voyage Home'. It is also a huge improvement over 'The Final Frontier', which wasn't that awful to me but by far the most problematic of the six (more so than 'The Motion Picture') and deserves its reputation as the worst 'Star Trek' film based off the original series, whether it is the worst overall counting the 'Next Generation' films is debatable.

Not a perfect film by all means. It is a little too talky in places with parts needing a little more clarity, while the ending felt rushed and overblown even if visually epic and exciting as well.

However, 'The Undiscovered Country' is one of the best-looking 'Star Trek' films, with a noticeably grander budget than the previous film, the sets are elaborate, the whole film is beautifully shot and the special effects are some of the most epic and most audacious of all six films put together. The film is beautifully, hauntingly and rousingly scored, a clever score with a wide range of emotions.

Returning a more than welcome return, Nicholas Meyer delivers what is by far the best-directed 'Star Trek' film since 'The Wrath of Khan', there is a sense of loyalty to the original series while bringing his own style without being too ambitious.

Aside from having moments of being too talky and not quite as clear as it could have been, the script is a perfect balance of provoking thought, genuinely funny and beautifully timed humour, humanistic messaging and affectionate lampooning. The story has a dark political tone, while also a heart-warming affectionate air and great entertainment value. Clever Shakespearean touches too.

The character development, interaction and conflicts were always where 'Star Trek' particularly excelled. All the main characters are interesting and more complex than usual, even Kirk, while the supporting cast are in character and much better used.

Leonard Nimoy demonstrates perfectly why Spock is one of 'Star Trek's' most interesting and iconic characters, while William Shatner wisely reigns in more than usual and gives easily his best performance of the six films and actually much better than the original series as well. DeForest Kelley and James Doohan are also spot on, Kim Catrall is not bad at all and Christopher Plummer is a superb villain (both menacing and fun, ties with Khan as my favourite cinematic 'Star Trek' villain).

In summary, outstanding, the original 'Star Trek' couldn't have had a better send off. 9/10 Bethany Cox

This film is the sixth film of the franchise and revolves around an attempt of peace between the Klingon and the Federation due to a serious danger that threatens that hostile empire. But what sets the public on the brink is that this is, truly, the last film of the franchise to bring the whole original cast. The years go by... even in the 23rd century. So it all revolves around the usual three main actors: William Shatner, Leonard Nimoy and DeForest Kelley were superb throughout the film and, thus, had the opportunity to close, in the best way, this part of their career (certainly the one that most contributed to make them famous and successful). The remaining cast, however, equaled the good performance of the three protagonists. The script, I confess, is a bit confusing, leaves a little to be desired and even makes us feel a bit sorry for the Klingons. The technical details of the film are roughly the same as the previous films, in particular with regard to special effects, but there are already a number of advanced and modern features that previous films did not have. The cinematography is also clearer, it seemed to me less misty than in older films. It's not a memorable movie, at all, but it's worth watching.
