Oh I actually REALLY like Michael and Holly.  They're so perfect for each other, which is why I was hoping Holly would hang around for a while.  But if we're talking about a relationship that bores, it's definitely Jim/Pam.  Ugh, I'm so over them.  Break them up (and write Jim off for all I care).  
 
But I agree with you, the rest of this season's been pretty great, it's just this last episode.
