Honestly I think this is the best thing to ever happen to the television set. The idea that the show can't go on without Jimmy is foolish. I can't remember a television program with such a solid lineup of interesting and invested characters. In my personal opinion, the writing, acting and production of this show sets a completely new standard for a television drama.
As an aside, they could have it go on for 100 more seasons, with actors from the year 2112 playing characters on the Jersey Shore, before I'll think it has run its course.
No but really, it is good.
