On the surface, ER and The Pitt may seem like very similar shows, but there are actually so many differences that viewers coming from the HBO series to the network medical drama may be a bit disappointed if they don't set their expectations accordingly. The Pitt is the latest medical series to take the TV-watching world by storm, and with The Pitt season 2 in the works, it seems that emergency-room-hungry viewers may have finally got the prestige show they've been waiting years for.
