Sorry about that. I tried to find the article I read on startrek.com. I read the article back in 2004/2005 when they first announced the show was being cancelled. In the article he said that he regretted not letting the lead writer go who wrote most of season 3. There was also a mention of it on the Histroy Channel, the show was 'How William Shatner Changed the World'. Towards the end of the show Mr. Shatner said, 'perhaps the decline of the Star Trek Series beginning with Deep Space 9 and Voyager later seasons. By the time Enterprise came to life the show was doomed.' Also said, 'perhaps the ultimate reason was because the shows writers had moved to far from Gene Roddenberry's original vision.' Those, unfortunately, are not exact quotes but it is the general meaning. Anyway, sorry about adding the 'opinion' vice the fact. 
 Have a good day.
