Well, this thread shows me how different can be interpretations. I never believe that there is a typical Star Trek "fan". So for me generalizations do not provide an informative basis. Here I can talk about my opinions.
I think fans would be perplexed at why the ENT Vulcans were acting so out of character and why are they sporting similar wigs? Why are they not acting like friends towards Humans???
We are talking about ca. 100 years before TOS. If I do not go far and think about how Europa looked like for 100 years before, from the cultural index to civil rights, from relationship between European countries to daily life, who can say everything is still the same? Why should Vulcan society be the same after 100 years? It does not make sense. Another thing in itself which does not make sense is the mode, inclusive wigs/haircuts, whatever. Even hippies have their dress codes. Why not Vulcans do have a certain hair cut at a certain time period? Question is, if Vulcan society concept at ENT reasonable and plausible? I would say, yes! They are on the way of evaluation to being Vulcan society who is familiar us from TOS and not only Vulcans, also Humans and Andorians trying to find their ways. This is "the" story of ENT.
Why does the NX-01 looks so ugly, why are they wearing those stupid looking outfits???
It is the question of taste. I love for example XCV-330, both Constitution class 1701's, Excelsior class, Sovereign class and NX-01 design and I do not like Galaxy class, Ambassador class, so on. It is my taste without any logical reason, no one must be agree with this.
Uniforms of ENT are the best, not like pajamas. They are very functional and cool. I know what I am talking about, at least I wear one of them three days at Con and had too many pockets for everything

I/we get too many compliments at among others from mighty Ms. Nichols and Vaughn Armstrong

Hihi..
Why does their engine room and interiors look far more advance than TOS when it's suppose to be a prequel???
Problem is not ENT but TOS. Already at 90's we have smaller mobile phones and flat monitors which TOS showed. I know many people they are Trek fans but they watched TOS as mandatory home work, not enjoyed as me. Main reasons are they find it soo retro and have issues with story telling of 60's. How could be a ship designed more retro than NCC 1701 but more advanced than our reality? It is a key dilemma. Another aspect is: Can producers call this show still scifi? Who will be shows potential audience? Only canon-belt Trekkies? Hey, we are talking about tough business such as money making kind of things.
Ahhh, how would be late 80's ENT? I am not sure, but Trip has definitely a mullet hair cut
