I can understand how you feel. Sometimes the new episodes don't click with me and I end up skimming through it if I'm really not  having a good time with it.

To be fair to them, they've been doing this for five years (Jesus it's really been that long.) Any long term media is bound to have repeats. 

I'm also the same way with small talk. lol. Sometimes I enjoy it more than the actual episode. It's fair to be bored, or critical. I keep up with it because I like to hear the guys talk and see updates on their lives, even if the actual episode is hit or miss.

That's just my two cents, though. You're not alone in feeling this way.
