I thought the Ent Vulcans were the most interesting iteration of the characters since TOS. One of my big gripes with the Vulcans is that they usually are shown to be too powerful. They outlive us, they're stronger, smarter, more logical, they don't need as much sleep. This is the reason I was happy to see Ent show us some way less than perfect Vulcans.
Then, they shouldn't have had "Vulcan" episodes, if they weren't going to write them the way they "are."
Here is the problem with the Vulcans; characters who are in complete control of their emotions provide little in the way of personal drama. If your show is a drama and you have some main characters who never show emotion, then you have a problem. Gene Rodenberry realized this and that is the reason he made Spock half human -- in order to be able to show the character reacting (with emotion, or struggling to control emotions) to dramatic situations. Rodenberry probably never dreamed that Trek fans would try to hold his Vulcan characters to an in-story ideal (total emotional control) that was merely a device to create drama.
The Ent writers did the same thing GR did but actually expanded the concept (emotional struggles) to include the Vulcan hierarchy. Showing the Vulcans as overemotional was explained by the fact that the Ent Vulcans had strayed from the teachings of Surak and the Vulcan leadership had gotten a bit too cozy with Romulans.
Just as GR did with Spock, the Ent writers had their Vulcan, T'Pol, in a lifetime fascination/struggle with emotional control. T'Pol in complete control of her emotions would not have been nearly a dramatic as the character we got. It is the same thing GR did with Spock, but he gets a pass, probably because he was the creator, but the Ent writers get chastised by "purists" who fail to understand or are just unable to look at the two shows objectively.
The Ent writers had a great idea. It is just too bad that so many fans didn't really understand what they were doing.
