Yeah, the first season was awful, which seems to be a very common thing among SF shows (see also, Babylon 5).
A large part of it, for me at least, was the constant retreading of original series stories. I got the feeling they were aiming for "See! This is Star Trek! Just like you remember from watching each episode dozens of times during syndication! Really! It is!" It got better when they got away from that and decided to do their own thing.
