I've only just discovered Archer and smashed seasons 3-8 so far. What a show! I noticed the drop off in quality but still a better than a lot of other stuff out there. Waiting for ABC comedy to repeat the first 2 series as I got in late.

Worth the wait or hunting out on Netflix. Seasons 1 and 2 are the best.
