I couldn't get through ENT. It was way too serious and "sexy" to be Star Trek imo. The characters also weren't quite diverse or amusing as all the other series. I get that it was set before many new species were discovered, but I would at least have added like a snarky companion robot, or the last of a dying species or something.
And all the sitting in the airlock in underwear wasn't really necessary either.
With the rest of your ranking I do agree. TNG was the best series by far, just because of the great cast and excellent writing (with some caveats)
This is it!
This is the picture I have been looking for so long! In my opinion, the best Star Trek joke to date
