As a lifelong fan of Star Trek, reviews are never a clincher for me. I'm thrilled when reviews are positive/informative, and disappointed if a critical review is harsh, but I'll still buy/see the product, no matter what. I can't imagine a time when I'm so angry/jaded about Trek that I'd refuse to acknowledge a new one.
As for the cool new look for the Klingons: if you put Kor, Koloth, Kang, TMP's Klingons, Kruge, Klaa, Chang, Worf, Gowron, Martok - and this new one - in a line-up, they are all different and yet readily identifiable as Klingons.
I'm looking forward to this next batch of "Ongoing"!
