You have the right to hold whatever opinion you like about Lex, Clark, or Lana. I personally thought season five was the best season of the show, and thought Lana underwent a lot of interesting character development when they finally took her out of the endless holding pattern with Clark and allowed all the character trajectories they've been developing for the past four years to finally come to fruition. I'm avidly awaiting the Lexana next season, actually. But I don't expect to change your mind about this, since you are famous in the fandom for your tenaciousness when it comes to your opinions about the show.

What I would appreciate, though, is that you not call Lana "that dog" in my journal. Frankly that seems to be crossing the line between valid criticism of the character, as you see it, and just insulting for insult's sake.
