I'd have much preferred more TOS backstory in the show than we got, but all things considered it more or less filled out the role and the shoes of a prequel fairly well. When it was all over, you could buy this was the era and century that led up to the era of Kirk and Spock even if some fans couldn't seem to get past the more modern set technology and "Akiraprise" design of the ship herself. ENT was flawed as all TREK shows have been, but at least I don't think it lived past its prime or squandered most of its potential the way VOYAGER did. And Jonathan Archer was simply...with all due and loving respect to Kate Mulgrew and Kathryn Janeway...a better captain and lead character than she was.
