It's reasonable to expect that we'll see the characters evolve and grow over the series. It's a highly serialized format after all. And, the producers have indicated that only the first season will focus on the Klingon war and that they wouldn't want a darker series for any longer. So, stay tuned!![]()
I do have to say this is a fair comment. I mean, I'm a Niner, but at the start of the series, many of the characters were downright annoying. In some cases, like Jadzia, it was because the writers hadn't found the proper role for the character yet, but in other cases like Bashir and Kira it was because they purposefully started off the character flawed in order to showcase growth in later seasons.
