Trip by a sector. He was a warm, funny, charming, bright and very human character.
Archer was a bumbling idiot who was a terrible captain who had no idea how to interact with alien races, became increasingly aggressive and hostile--but then again since he was beaten up by almost every alien then encountered maybe its understandable why. They were trying to make him out to be some great hero when he simply wasn't.
As for T'Pol, it made sense to have her on board and she had an interesting arc, but she was poorly cast. If an actors idea of being emotionally detached is a pout then there are going to be problems. Add to that the totally unnecessary (and hideous) catsuits so that rather than being seen as an intelligent and logical character she is little more than titillation for fanboys.
