visually I could understand what you're saying but factually ENT lines up the least with every other Trek.
That was inevitable if it's true but irrelevant when one considers this; while
Enterprise might not match up perfectly with the other shows,
Voyager never managed to match up with
itself and we still consider that canon,
The Next Generation has effectively been retconed on several fronts by
Deep Space Nine yet we still consider that canon (like the Ferengi and the Trill being completely different on DS9 than they were on TNG for just two easy examples), so the idea that a handful of things don't fit with the other three being used as source material to discount
Enterprise as canon seems unfair at best.
VOY: Already stated that the NX-01 was named Dauntless by the Alphanumeric tradition. It's the first Lettered ship we've seen outside the Enterprise Lineage. Why they decided to do otherwise is beyond me.
I can't put the fate of another series in the hands of the Voyager writers. They white wash their
own canon as often as they add to it as a whole... so, if I have to disregard the Borg Baby, the cure to assimilation never being mentioned, and all the other things that I have to in order to just enjoy Voyager, I can disregard that too as just another of their many, many, many continuity mistakes.
DS9: Stated that there were only 6 starships named Enterprise
They, at one point, also said there were
five ships named Enterprise. Sisko and Dax have called species by the wrong name, and the Sao Paulo had the same registry number as the Defiant. Mistakes happen. They get stuff wrong.
TNG: The Thing is TNG makes no mention of any other ship called Enterprise and it to refers to only 5 Federation starships with that name.
Actually, they do. The episode came a little later than all the others but it involved Troi and Riker visiting a holodeck recreation of Enterprise. As I recall the entire cast of
Enterprise reprized their roles for that episode.
Whatever the case, Enterprise is canon, and I can meld it with three of the other four series pretty easily. The only one that doesn't match, in that case, is TOS. I'd be happy to just toss it out as another ham fisted show from the 60's (like the original Batman or Hee Haw) but there are the movies...which, without, I think most people would forget about TOS and this on-going trial about Enterprises' status as canon or not would never have started.
