I don't miss him one bit. It almost seemed like we were going to get a peek into the tribal aspects of the the others through Karl... but the story went a different direction. If I remember correctly, we met Karl right around the same time as we witnessed Coleen's funeral and witnessed Juliet's trial.
As a result, the character to me seemed flat and shallow. Practically useless IMO.
I'm sure the actor is great... but Karl the charater... bon voyage!
It's Karl with a K. As for the question at hand, no I won't miss him. I don't feel he brought anything to the show, Alex is by far the more interesting character in that relationship. And technically Alex had to convince Karl to go tell the Losties about the impending attack, so he's not exactly that heroic in my eyes anyway.
I'm not really going to miss Karl either, but I didn't think he was a bad sort...I mean, I don't think he deserved dying. However, I think killing him off will take Alex's character in more interesting directions.
I always thought Karl might have been the product of a Dharma experiment gone bad. LOL!
There was just something about him that seemed "off".
He just didn't seem to fit with Alex. She's beautiful,spirited,strong, and the leader's daughter! She deserves better! Although,there did seem to be a lack of males anywhere near her age on the Island.
He served his purpose. There wasn't a lot of depth to the character but I guess there didn't need to be. I didn't find him annoying or anything. He was a pawn in examining the relationship between Alex and Ben.
And one other reason I'm glad he's gone... it, thankfully, eliminates the possibility of another Jacob-awful quadrangle of Love (Danielle/Ben/Alex/Karl). I think there is very meaty stories to be told between Danielle/Alex and Ben/Alex as well as the interaction between the three. Trying to throw in the whole teenage love story too?!! Ugh... no thanks.
