In many ways this is a typical episode of ER, showing a cross-section of stories and how the usual cast members are affected while further developing the background stories of each series character. There are nice (even if sad) wrap ups to some ongoing story arcs, but more than anything else, as the episode comes to an end one is reminded that this show reflects real life so well, and that while you may be looking at a snapshot of a period of time in the ER, the real story will keep going even after you are not watching. And in that sense, this typical episode is such an excellent close to this series. Some more cynical than I am might suggest that this leaves the producers an opportunity to bring back future episodes (1 year after ER closes! Guest appearance by George Clooney!!) but I hope that that kind of thing won't happen. The ER series wasn't perfect by any means, and although I watched it religiously at the beginning, I admit my attention wavered at times for months as the cast or focus of the show changed, or as my own real-life interfered with my TV viewing. I didn't necessarily get all my questions answered about what happened to X (insert a cast member's name here)? but overall, a very satisfying end to a remarkable series.
