No, George Clooney did not show up for the series finale of ER.

But it was a pretty good finale anyway. It's impossible to please all fans of a long-running show in a series finale because we expect too much, and what we expect can change depending on whether you've been watching it since the beginning or just started four years ago. Do they focus on the old cast members coming back and focus on the people who have been there for the past few years? Do they tie up all loose ends neatly in a bow or leave things open-ended because that's how life is? ER managed to do both last night.

After the jump, the good and bad about the last episode of ER.

Yup, tonight is the final ER. NBC will have an hour-long retrospective at 8 PM and then the two-hour season finale of the show at 9 PM (sorry, fans of My Name Is Earl, The Office, and 30 Rock). We've seen several old favorites come back this season in previous episodes, and we know that a couple more are coming back for tonight's last hurrah. Will George Clooney be one of them?

Clooney already made an appearance on the show with Juliana Margulies a few weeks ago, and I liked the episode enough. It's just that there was a slight something missing from the episode, something concerning Doug and Carol and them not knowing that the kidney going to County General was for Carter.
