No. And contrary to popular belief, I don't believe that overall the writing or produce's decisions had that much of an effect overall because if you look at the series objectively - it was as well or better written then the rest of 'modern' Star Trek.
Hell, writing and decision-wise, TNG was virtually unwatchable and POORLY written to 2 1/2 seasons. Why did it survive to be the one Star Trek series with good ratings who started to GROW its audience in season 4? Because people had been WANTING live action Star Trek back on for 18 years (1969-1987; and I don't include TAS); so they were willing to let the series find its legs; and a new generation of viewier obviously enjoyed what that saw - and MORE of the geneal/casual type viewer caught the show and stuck with it for a time.
TNG was somwhat of a fluke in modern Star Trek. I say this becaause if you look at TV ratings trends; decil in Star Trek viewership overall STARTED with Deep Space Nine (considered by the majority of folks on this BBS to be the 'best written and produced Star Trek series); YET DS9, VOY and ENT ALL had similar decines in viewership (percentage wise) over each of their runs. Kell, at it's lowest viewer points (in season 7); DS9 got only 4.77 million viewers - YET NO ONE questions the overall writing or producer decisions (Hell, there's the 'Is Ron Moore Star Trek's Greatest Writer' thread up in the 'General' forum as I type this - and further, nu BSG, Ron Moore's 'baby' who most everyone still fawns over the writing has ratings so low that some repats of ENT on Sci-Fi have BEATEN it).
Yet, again, here we are with yet another thread basically claiming "If only ENT had been written better, it would still be on the air (completing it's seventh season as of last May); and 'Star Trek' in general would be 'going strong'.
Bzzzt! False! What killed ENT early (although I still fail to see how four seasons of ANY series in today's TV landcape can be considered a failure; (and again, I point to the often touted nuBSG - which by many here is considered a 'success'; yet it's ALSO ending at 4 seasons with 78 episodes - ncluding the two hour 'Razor' film); was the inverse of what kept TNG alive back in 1987. Namely, the fact that 'Star Trek' in some form had been on the air for 18 years straight (and produced 25 TV seasons worth of episodes equalling 600+ hours of television); and the general public simply got tired of 'Star Trek'.
Belive it or not - this happens. I honestly cannot believe that some fans think that 'As long as the writing is top noth, people will watch...'
Again, if you look at TV viewing treds - not true.
What killed ENT was the fact that Star trek now had 25 seasons and 18 straight years of episodes; combined with a regime change at BOTH UPN and Paramount/CBS that:
A) Felt Star Trek was not drawing the demographic the (now dead - or combined into the CW with the defunt WB) UPN Network was going for.
B) Felt that with 600+ episodes; the Studio could make MORE money just selling the syndicatio and product marketing rights - WITHOUT continuing to bear the cost of producing new episodes.
I LOVE TOS (in my book the #1 Star Trek series; with ENT a close #2); and can say without a doubt that overall, ENT was fairly well written from day one.
It's first season was MARKEDLY better then the first seasons on TNG, DS9 or VOY; and it's second season - which I agree had a run of some atroscious episodes in the middle of it was still better that TNG's second season; and about on par with DS9 - I stopped watching VOY entirely after it's first season so can't comment there.
ENT's third and fourth seasons were on par with the best from TNG and DS9 - and I would go so far as to say ENT's 4th season was the second best season of Star Trek produced in the 40 year history of the franchise (the best season imo being TOS' stellar first season).
So, given that the fourth season of ENT was delivering very good stuff (again imo); I hink it shows that 'better/sifferent' writers would not have made a difference.
18 years of constant Star Trek and the regime shift at Paramount/CBS did ENT in more than anything else.
Lastly, for those of you who might be asking - "Well, if that's the case; why did Paramount greenlight anothe 'Star Trek' film?"
basically, they didn't per se - they had a development deal with JJ Abrams; who came to them and said "Hey, I've always wanted to do a Star Trek movie and have this idea..."; which Paramount liked and decided to go with. If it wasn't for JJ Abrams, I seriously doubt Paramount would have even considered another Star Trek project this quickly - or doing one that goes back to TOS and revcasts all the major character roles.
But, I've gone off topic a bit here. In the end, to reiterate my answer to the question - given all the above, I'd say the answer is 'no'; and I even find the premise of the question wrong as overall - the writing staff of ENT was about as good, or better than the writing staffs of all previous modern Star Trek series.
