Enterprise is off to a good start, but it'll take some time - I hope they start giving a little more backstory on Earth's "history" between now and the start of the series. But give it some time - I watched some of the early TNG episodes a few months back on TNN and I'd forgotten just how many bad episodes there were in the first two seasons.
I still think that while TNG had the best individual episodes, DS9 was the best as a series - it had the advantage of plot lines that carried over several episodes, and even from season to season. (Of course, just voicing an opinion like that risks setting off a Trekker war on the boards...sorry...)
