That's definitely the case in the last four seasons. The first three, not so much, but those seasons were boring plot-wise so I don't blame you if you couldn't sit through them.

...Yeah I have no idea why I like this show. I hate the main characters, I hate the writers, and I hate that I keep watching it and hoping that the two characters I DID like will reappear and survive the angsty makeover everyone's been given.
