Not a fan either, but then to each his own. In the world of Star Trek there are a wide variety of takes, designs, opinions, opinions about designs, and whatnot. You, as the audience member have to decide what you feel is consistent, or relevant in a lot of instances. That said, here is how I personally view this design as a designer and artist. First, its well executed (for an example of poor execution look no further than the Klingon D7 from the Remastered TOS episodes), but there are problems if you are looking at this as the original
Bonventure from TAS. First, its livery is all wrong. If it came out before NX-01 or XCV-330 (whatever your take on Enterprise is) the livery is apropos to a much later vessel, say from the 2230 - 2240s era. Speaking to livery as an aside, if it was an earlier ship I would have been happier to see some UESPA markings, but alas such is not the case. Moving on, the features of the craft itself (the bridge/command forecastle, windows, general shape and design of the primary hull, and the intercooler loops on the nacelles) speak to it being a much later vessel from about the same period given for the livery. Also, I find the fusion of the secondary hull into the primary very.. jarring. I'm not a big fan of intermingled hull forms- so aesthetically I would say this would be one of my least favourite designs. That said, Meni may have been alluding to a early Enterprise design sketch, which you can see here..
I do not know if that is the case, but there are enough similarities between them that I make note of them. So, in summary- does it fit as the starship
Bonaventure from TAS, I'll answer with a qualified no. Could it be a later
Bonaventure named for the earlier exploratory vessel? Sure, it could be, but in my own little world I don't acknowledge it as such, and that's my POV and I'm sticking to it.
Oh, one last thing.. TAS'
Bonaventure is far from perfect, but to give you a look at it "in the flesh" so to speak.. here you go.
