My favorite thing about Enterprise is Vulcans. In this series, they seem more real, they seem closer and just cuter. Honestly, I found more than one favorite Vulcan in this series (Soval, T'Pol, Mestral, Yuris, all V'tosh Ka'tur...), while in the other series I didn't have any... well, maybe except for Sarek...
My favorite thing about Enterprise is T'Pol. Because she's a cute and curious character. I liked to watch the development of her character, for her rendezvous with the crew. And she's a Vulcan, which is a plus for me. Atypical Vulcan, it's double plus. She's good... this is the main thing...
My favorite thing about Enterprise is Archer. The most beloved captain of the entire saga, honestly. It is interesting to watch someone who is not perfect, who makes mistakes, but continues to go forward and does not lose faith in themselves and in their mission. I like this captain the best, because he is kind, good, simple and understandable, does not get smart and shows emotions, values every member of the crew and wants to be friends with everyone. The most important thing is that he has a charming doggie!
My favorite thing about Enterprise is Porthos. Comments are unnecessary. A charming little doggie! This beagle always pleased the eye and raised the mood.
My favorite thing about Enterprise is "Faith of the heart". In fact, I think this open credit is gorgeous. Music, video - everything is beautiful and good. Much more interesting than to contemplate the outer space and a flying starship...
My favorite thing about Enterprise is "Fusion", "Carbon Creek", "Stigma", "Fallen hero", "Cease fire" and all Vulcan arc.
