For the most part ER is an exciting, well written television classic that is worth the watch and the first eight seasons were by far superior to than the seasons that followed. At first the characters were compelling and displayed a wide array of clashing personalities with all the usual TV fodder of blooming relationships and shocking moments. The three leads of Anthony Edwards, George Clooney, and Sherry Stringfield complimented each other excellently and led what is probably one of the biggest supporting casts in TV history and certainly one of TV's all-star casts from top to bottom. The early seasons did have their few issues, none bigger than Weaver who by sheer will of the screenplay always failed up without any consequences. There was a clear demarcation when Anthony Edwards left the series and no longer having a compelling lead they settled on Noah Wyle's Carter to be the new lead; which while a good secondary character was not deep enough to lead the series. That is why it appears that the writing staff began to focus on by far the most insufferable character to ever grace TV screens: Abby Lockhart. Tierney's Lockhart (not a knock on her she played it well) almost from the onset monopolized the screen time and the storylines featuring her annoying family were a real turn off. I can't imagine how trying it must be living with a bi-polar family member and I'm not making light of that fact but we could have used a much more streamlined arc because it just seemed to drag on forever. Later in the series she was given a run for her money in the worst person ever division by Neela and/or Sam and her son. All three were screen hogs that embodied the example of a narcissistic, perpetually spoiled child that only grew up physically but never emotionally. The later seasons also featured loads of ridiculous storylines. One season Sam's son runs away, the very next season they get kidnapped and she has to murder her ex-husband. To further add insult to injury she is never arrested or tried despite the fact there is a police investigation and she is clearly guilty. If they wanted to play that storyline then have her get arrested, go to trial and be acquitted. That would have been more believable than the absurd writing which bordered on parody. The parodic storylines were even talked about by some of the characters themselves during some of the more absurd medical 'emergencies'. For reference just look at the Romano helicopter storylines! The series also became peachier and leaned heavily to the left as it went on. For reference just look at the African storylines featuring Kovac and Carter and how every Christian character was always the weird, intolerant bigot while the atheists were always compassionate and indignant of those 'religious fruitcakes'. People have different opinions and writers even back then were already inserting the social justice message into their series even if it wasn't called by that name. I can be honest in saying if I had watched the series week to week when it first aired it would have annoyed me to the point where I would have stopped watching but since I streamed it I powered through the deficiencies to watch it completely. If it fits to your ideals or you don't mind sitting through seasons of rough watching then give it a shot.
