Larry come home

Ive watched all of the new seasons show and I have to say they're mediocre at best (although they're better than 90% of the crap on tv ie the single guy) I think the problem is the departure of Larry David. Jerry is a good comedian but I just dont think he's up to the task of running the whole show himself. I dont think Larry David got as much credit as he deserved for the success of Seinfeld. The characters seem much different from previous years and the stories lack something. Unless David were to come back (highly unlikely) I cant see Seinfeld lasting much more than 1 more season (not due to lack of ratings, but because Seinfeld will have had enough of the show) So whadya think?
