Here we are, the end of the Star Trek films featuring all of the original crew. I have been impressed for the most part with the whole series, at least much more than I had expected. I never had a problem with Star Trek it just wasn't something I ever really got into. From what I've read, Part 6 seems to be considered one of the better entries of the series, and though the cast is visibly getting a little old for this, they still manage to kick some butt (and get their butts kicked too).
The Klingons are soon to become an extinct breed if they cannot find help from other planets. The Federation, who have been at war with the Klingons have decided to help. Shortly before retiring, the original crew of the U.S.S. Enterprise try to be civil with the Klingons and invite them on board their ship for dinner. After the Klingons return to their ship, they are suddenly fired upon by the Enterprise and two mysterious assassins come aboard and start shooting the Klingons. The crew of the Enterprise has no idea what has happened and beam Kirk and Bones aboard to try to help. They are then arrested by the Klingon General Chang (Christopher Plummer), found guilty by the Klingon court and banished to a slave colony. The remaining crew of the Enterprise must find out who really fired on the Klingon ship and prove that Kirk and Bones are innocent.
The Undiscovered Country was a great end to the original Star Trek series. As I previously stated, the crew are looking pretty old and it's good that they knew when to quit. That being said, this movie has lots of action, especially the scenes with Kirk and Bones on the slave colony. They must travel through arctic conditions and get their asses kicked by alien inmates. The whole whodunnit/wrongfully accused plot works very well and the film's special effects are very impressive. It's also great that Nicholas Meyer, the director of Wrath of Khan, returned for this film, one of the most action packed since Khan.
