I love TOS, it's a close second for me to the TNG. I'm 26. I think TNG and TOS are in the same vein. What I like about TOS as with TNG, are the characters and their interactions. I think that interaction is only seen in TOS and TNG. The spirit of the show is also similar to TNG and the fact that it is an exploration ship. Both TOS and TNG really hold true to the oppening speach at the begining of TNG/TOS more so than the other Trek shows.
