Oof yeah those last episodes of voyager are rough. Growing up with TOS nostalgia keeps me from being able to give an objective opinion on it. But I will say this. If you are enjoying some of these other series, it spawned them all for a reason. Enterprise was okay. I wouldn't rate it any harsher than most the rest of the series. Though the opening interstitial and theme are pretty solid.

I haven't watched much past enterprise myself or the first couple of seasons of DS9, which I hear were some of the worst of the series. Too little Jeffry Combs you know.
