But I do like some things. It looks good. The CGI isn't half bad. And I like how it ties into TOS, though there are some lore inconsistencies. Like a Klingon D7 battlecruiser a 100 years before they are even introduced in DIS season 2.
The producers often took designs and designations from the old tile game Starfleet Battles. That's definitely where the D7 designation came from, and the D6 and D7 were basically identical from the outside. Different weapons and other systems, but the same hull design. You could make the case that the ship in ENT was a D6, albeit a brand spanking new one, I'd imagine. However, the model they used was actually a K'tinga class cruiser, blowing that theory all to hell.
According to Memory Alpha they created a new model to use, presumably a D5, but the producers didn't like it and had them reuse an existing model.
As I recently pointed out, I found ENT far better than I remembered, with S2 probably the high point. S3 was inconsistent, but had the best episodes in it. S4 is half pretty good and half unwatchable garbage.
