I grew up watching Trek in the 80's and 90's and loved Roddenberry/Berman Trek, I've noticed he gets some flak for the demise of Star Trek which in my opinion is unfair.
I think it is perfectly fair. The previous series featured a lot of strong personalities who were willing to fight with Berman over ideas, and Berman, for the better, had more ideas from which to choose. By the start of Enterprise, most of those writers had left, in part because they tired of fighting with Berman. As a consequence, Berman was more in charge of Enterprise, and Enterprise seasons 1-3 reflected his style and personality more than any other series.
