Interesting how opinions vary because the love for Barney utterly baffles me. He's, IMO, the weakest character on the show and just gets increasingly more vile as the show goes on. I liked Ted the least at the beginning of the show, but he improved over the years while the rest of the characters regressed, particularly Barney and Robin and their toxic relationship. I haven't finished season nine yet as I'm watching at E4's pace, but Lily and the mother are currently the only characters I'm enjoying. Shame, because I really loved the first four seasons.
