We had stumbled upon the show on cable one afternoon and got hooked on the 3 episode block from season 4. So we looked it up and found MAX carried the series. We pulled it up and dove in.
It's odd, the older episodes are the ones remembered better. George Clooney in a sewer with the kid? Remembered it. Dr. Lewis leaving the show after only a season and a half in? Remembered that has being a big deal that an actress left a successful show so suddenly. A whole episode about a guy with a bad heart dying? Yup. ER birth gone wrong. Oh, yeah.
It started to become apparent that they had this stellar cast, and it would seem Mark Green was the heart of the show but the story of ER was going to use the newbie Dr. Carter as it's through line (one way or the other).
Cast members I thought had been there from the start turned up later in the season (Kerri, the bossy one). They true constants were the support staff, the nurses which would wander in and out of episodes and seasons and suddenly re-appear after being missing for a while (they often said, "Oh, I was on night shift.")
Then they started writing themselves into corners. Actors wanted to leave, so they would, leaving their support cast in the lurch. Clooney leaves Carol with twins. Green marries Benton's old girlfriend. Carter cycles through a number of interns and they would leave, move on or get murdered. In a late season episode, they bring in a new desk clerk announcing the two previous desk clerks, Jerry and Randi, are gone and can't cover. Jerry had come back only to be shot in an episode and Randi, who hadn't been seen in an episode for years, just disappeared, which was odd, because she seemed like a minor character who lasted for years on the show.
Pop culture references were frequent; SNL quotes, some current events and then they'd do the "very special" sweeps episodes where a plane crashes or they run off to Africa. The patients coming in were essentially old people, gang members and the occasional pregnant lady.
The show had a habit of setting up a conclusion to one sub-plot and then totally dismissing it in the next episode. Carol decides to earn money with a worm farm she rescued? Next week, the worms are dead. Sam gets a job working as a private nurse for some rich guy? A few weeks later we are informed "it didn't work out." Alex saw his mom shoot his dad dead, he got over it (instead of holding it over her head forever).
One mid-run episode, they introduce a character, a good looking doctor who they learn masterbates a lot. They reason they introduced him? So they could make a "Grey's Anatomy" reference, nicknaming the doc "McCreamy."
A season or two later, they introduced another bald, nasty surgeon character, but this time he was more of a cartoon character who got into a kinky thing with semi-regular Sara Gilbert, recently escaped from "Roseanne."
The show often brought in guest stars to do a "sweeps weeks" story arc; Alan Alda, Don Cheadle, John Leguizamo, Bob Newhart. Then later, they'd have guest stars for odd one-off stories with them as the center, Cynthia Nixon, Ray Liotta, James Woods.
As we got into season 13, they were trying to hold the show together. All the original cast was gone. They transition from 90s TV with an opening theme and credits to just a title card and the credits run over the first scenes. And, then, to pull in the new viewers, the changed the theme song. To something bad. The original theme and soundtrack music was a driving pulse of the show, to the point that when they did a gimmicky live broadcast as the opener for season four, the had to replicate the soundtrack by having some guy with drumsticks start banging out a rhythm on set when they had a fast-paced medical trauma.
Also, a lot of stunt casting as the ER goes through department heads like Spinal Tap went through drummers. And with so many characters having had on and off relationships, they had to start blending new characters into the mix. There were a lot of "Cousin Olivers" showing up for brief cycles.
I think the series jumped the shark mid-way through, in their version of a "bottle episode" where five of the cast have to attend an HR training session. The teacher is late. They shoot the breeze and two of the characters wind up in a sword fight. Just because.
In the last season, the new head of the ER, Angela Basset, has a flashback to the time she her child died in that very ER, and Mark Green, Keri, Romano and even Jerry appear. Then Jerry comes back to his old job, replacing the guy who was from the first episode who Jerry had replaced.
In a later episode, Carter returns because he needs a new kidney. The donor is in Seattle. Guess under whose care? Ross and Hathaway! But while they meet the new cast members who show up to get the kidney, they are never aware Carter, from their time on the show, is to be the donor recipient. Talk about viewer interruptus!
For the season finale they brought back many of the characters from the run of the show, with cameos and guest appearances and the show even brought back one of the nurses simply to recreate the opening scene from the first episode. And then, to bring it full circle, Dr. Green's daughter shows up as a medical student who Carter decides to mentor and they recreate a Dr. Green/Young Carter scene from the first episode.
It was a great show, that devolved into a very good show after 15 seasons. And you have to remember, this was back when a season lasted 30 episodes or more. But we did it. Now we just have to catch up on all the shows we missed while we were doing it.
