Enterprise was done dirty. They should have been allowed at least one more series to deal with the romulans. It was just starting to get good.
Sure the character of Jonathan Archer was a complete idiot who shouldn't have been allowed in charge of a light switch. But that kind of makes sense because it was only given the job because of who his dad was rather than because he had any skills. No human knew what they were doing at that point in time because no human had really had any interaction with any alien species yet except the Vulcans.
