The movies of the even I like the best are:
1.The Voyage Home: I love this movie because not only its exciting but its very fun. I also love all the comedy in it which was kind of first for Star Trek movies, but it still workd really well. This movie kind of reminds me some of the episodes of TOS a lot. You know the time traveling,and allen being thats like a machine. I remmber in some old episodes of TOS where they traveled back through time, they had to do thier best to blend in with the time without being discovered. But they sometimes slipped and got caught anyways and had to explain without disrupting the timeline.I also like this movie as Spock is trying to rediscover who is after reuniting with his Katra which got part from him in TWOK which he gave to McCoy. It kind of reminds me of the episode "Spock's Brain" wich got parted from him then suddenly back with him.
2.The Wrath of Khan: I think its great movie as it has a villian which was from TOS. And the crew again has to fight aginst him, but this time with a price. I think by the end where Spock risked his life to save the lives of his friends, was very sad and touching moment. It shows his friendship with Kirk and McCoy. He gave his Katra to McCoy and then later has a very touching momnent with Kirk as he is dieing. It is real powerful scene. It really shows how important his friends are to him. I really love this part "I have and always shall be your friend. Live long and Prosper". It also very sad, but it just the begaing of what is about to come.
3.Nemies: I think this a good movie but very sad as we see Data die.I think this movie is the most dramatic of all TNG movies put toghter. Its also sading to see all of the crew go on to other things, not stay toghter as one. Unlike TOS crew who all stayed toghter until the very end exception for Sulu.
4.Undicovered Country: Its good movie but also the last for the crew of TOS, which is sading. But I admire them they did stayed all toghter as friends and crew until thier ship was about to be decomishened, in which TNG crew went thier seprate ways long before that. But the TOS crew even some got promted, still insted they stay with thier orginal crew mates except Sulu, but the rest stayed until the very end. Anyways some of the scenes in the movie are very good and touching, espichally near the end where finally Fedaration and Killgions finally agreed to the begaings of peace. "You restored my fathers faith" "And you restored my sons".
5.First Contact: I wouldnt say its my least favorite because it is better than TMP. Its a good movie, it has its moments. I love some of the scenes with Crochun, because its just funny.
