It seems like we just started with Season 3 and now it's done. I guess that's a 13-week season for you. It took 15 weeks to show and that was only because the Olympic Games got in the way. I like this show and it's done well given how they reinvent it for every season.
We know one thing will be different and that's Oz' job. Thanks to Sandy, he will no longer be driving an ambulance. That's probably going to be a good thing as it centralizes the show in two places: IIB and the hospital.
I thought the season started a bit slowly, got better and ended just when it was hitting its stride. I'm looking forward to Season 4.
