But for real? Of the cast I recall, they are both two that I most disliked. Deathstroke was some squat little aussie who never seemed remotely threatening to me. And I just out and out dislike the actor who played Merlyn. Though the character was written well. I dislike Moira his mum as well, mind. But her run was finite. I didn't like Kaitie Cassidy at first but grew to like her later on. Whilst Felicity had the opposite trajectory. The show did go downhill at a little in the middle seasons and that little Russian guy was wholly unconvincing as a Russian mobster. But the show picked up again and imo it ended on a high.
