This is one of my favourite seasons of ER. Sure by this season it had lost all of the original characters, but they really made the most of the characters they have by giving them fantastic storylines. The finale for this Season also one of the best finales ER has ever had. If your a big fan of Abby and Luka as i am, then this is the season for you*****

I feel that in season 12, ER lost a few bits on why we love it! At the end of the 22nd episodes i felt i had watched nothing happen! Season 11 was the end of ER for me with the two remaining cast members from season 1 left ER(Carter+Lewis)! in 12 it was different, they focused to much on personal lives outside the ER, but in previous series they balanced it a beautie! I feel that their wasn't much trauma action than in the others which is the biggest shame because that is what ER is all about! Also With losing Benton,Romano+Corday they lost the balance between ER+OR which is a shame! They also lacked a big cast! When Greene went it was different but Carter carried it on, with him now gone i feel the reaminig cast don't quite cut without Carter or Greene! Still watchable but for me ER is season 1-11.
