The episode shows that Surak most likely merely wanted the Vulcans to suppress their "bad" emotions. He wanted peace and logic, not total emotional suppression.
But the episode also showed how dangerous it can be for people who have grown up in the orthodox Vulcan culture to "let go". It took Spock decades.
About the Vulcans in general, well, they behave more or less like Vulcans. Vulcans have always been a bit arrogant and racist. What's different though is Vulcan politics and as many posters have already said, we learn why the High Command is so unenlightened in the last season.
I am glad that they didn't just do the usual stuff with the Vulcans but actually tried to be different and tell a new stories about them.
