Maybe you changed then, because I see Worf as being basically the same in the two series.
I'm confused. First you said....
BTW, Worf seems to have made significant progress, but only if you include both series.
But now you're saying he's the same and hasn't made significant progress ?
Anyway, in TNG he always seemed to me to be quite petty and severe not to mention extremely dumb. He lacks humour and experience and makes assumptions. In DS9, he just seems to have developed a lot more. He's smarter, experienced, more open minded and more capable of seeing the bigger picture
OH come on! Worf's idea of a joke (in the season finale, no less!) is to say "I am going to kill him" to Ezri, about Bashir. You call that a sense of humor?
You know it's like what Quark says in the end of the finale, "The more things change, the more they stay the same. "
I believe that applies to worf, to a T.
He's changed in the way that his manners have mellowed, he's less aggressive ect...
But when it comes to the basics he's exactly how he always was.
