I think this is wayyyyyy better than Seinfeld, namely because you can see just how much a contributor to Seinfeld's success Larry David's writing really was. Leon is the Ari of Curb Your Enthusiasm. Sorry CK, Gervais, Rock, Burr and company, this guy is the king master of them all, bar N O N E. Stoked for the new season to begin.
For me this is a top five show of any genre; while I usually like my comedy dark and fucked up, there is no show funnier than Curb Your Enthusiasm. Every series has been fantastic. I've watched them over and over.
