1) I am with G-Man on the shuttles, I hated, hated right from the start how Voyager just picked up from TNG and DS9 on shuttle respawning. The whole point of the show was a starship cut off. Completely cut off from resupply. Yes they occasionally gave nods and winks to that premise but the premise demanded so much more, in fact the premise demanded Farscape and Firefly. I wanted the Delta Flyer every week. I wanted shuttle pieces all over the shuttle bay every week as they desperately tried to keep one shuttle up and running. I wanted WAAAY more then one episode where they land to make repairs. I don't need a whole actof landing just open with the ship already landed. Gaaah.
2) I hated the way the Caretakers and Ocampa were swept away like so much else that was created for the show (hey remember that whole half Marquis crew thingy?).
3) Kazon and Water. Ugh.
4) As a Star Trek fan I don't think I will ever fully recover from Voyager.
The Kazon had water just because one tribe didn't have alot of water doesn't mean the rest of the various were short of water. The Caretaker and the other Ocompa did resuface in later seasons and there was never enough Maquis for them be half the crew over the year we only saw about 11 Maquis and two of them were spies, that's a huge crew for such a small ship in the first place.
