My spouse and I were talking about this last week. We came to the conclusion that as good as ER was, it was more of a network drama than the uber-competent fact-based show The Pitt is, and that in the end we’re glad it’s a new show with a new setting and an almost entirely new cast.
Gotta side with Warners on this, Crichton is dead and his estate certainly doesn’t own emergency room tv shows. They probably overplayed their hand in negotiation, and in the end I’m glad it’s a new show instead of a reboot.
