Who is your least favorite Star Trek TNG main character?

I'd have to say my least favorite is Tasha Yar. I was going to say Wesley, but there are some later episodes where he's not around his mother that he's okay. Tasha was just a bad actor. My favorite is Captain Picard, he's just a great actor and he holds the whole show together. Data is a good actor too, but only in support role. He doesn't hold the show together like Picard.
