You have to suspend your belief for pretty much EVERY television show to some degree.  Even a masterpiece like The Wire had me suspending my disbelief a fair number of times despite its very authentic tone (specifically hamsterdam and the homeless murders threads).

The point Noel is consistency.  This season was so far 90% as good as last season IMO, and the last two episodes have been AS GOOD as any of S3's (and I just re-watched it all last week).  The flat out refusal to give it an A despite VERY MINOR flaws it has is becoming infuriating.

I wouldn't care about it as much if they actually graded consistently.  But last season they give 9/13 episodes A, and this season they've refused to give this or last episode one, when they are SO FUCKING CLEARLY the best episodes of TV I've seen all year.

In the immortal words of GOB… OH COME ON!
