Larry, Leon, Jeff and Susie fly to Atlanta for Larry's much-publicised trial. Old friends join them in what becomes a quite the event. The prosecutor is a wily foe and soon things are going quite badly for Larry. Many old enemies resurface.
A finale that, like most finales, is quite nostalgic and captures many of the great moments in the history of the series. It very quickly starts feeling very Seinfeldesque in its plot and approach, which initially made me a bit disappointed, figuring it was unoriginal.
I then realised that this is the point: Larry David is taking everything full circle, linking Curb Your Enthusiasm's roots to the end of Seinfeld. Jerry Seinfeld even appears and has a decent amount of screentime, just to ram the point home!
All in all, it's quite funny (though, like Season 12 in general, not quite up to the same standards as recent seasons), nostalgic and ties things up quite neatly.
