This Star Trek Geek's opinion: Voyager sucks!
YMMV
Ahem.
Early seasons of TNG?
And I'm not saying Warp 10 wasn't Warp 10, but there were redeeming episodes, especially with the Doctor.
Hey, I liked TNG all the way through. It had that campy TOS vibe at first, but then it matured into my favorite series.
Voyager was so far removed from everything (by design). The fact that it was on the other side of the galaxy made it lose a lot of the draw I had from TNG. Some of the best episodes of TNG had to do with the federation and how the crew fell into the overall plan, most importantly the prime directive.
The Doctor bugged me more than any of it, actually. He was way too "human" to be an AI program. I mean, Data was supposedly the most advance AI ever, and allegedly nobody could replicate his technology. He still struggled with all kinds of relatively simple human interactions, and that was cool. This AI doctor was more human than Data from day one and he was some standard holographic doctor program installed on every new ship. All he was missing was a real, physical body. Then they fixed that by making a remote holo-projector, so he was pretty much just a member of the crew.
