The only huge issue I had with them was their makeup was so thick the actors clearly struggled to act through it. Contrast to such expressive Klingons such as Kor, Gowron and Martok which was very difficult to do when you can barely move your face.
If that hadn't hamstrung the actors so much, I think they would have been more enjoyable than people found them.
What they missed out was this is actually a Borzoi class support ship. Its slim pointed shape allows it to retrieve items such a ambassadors or pringles from the far end of micro wormholes.
