Well It is a fast paced view of EMS but going out and holding the hands of the taxi ride that makes up most of EMS calls would make for a very boring series
To answer your question based on what I saw..... what a joke.
What would I do in making a series? I'd take more cues from Southland, make use of blended story lines with varied involvement between them, and I'd try to find a writer who didn't treat the audience like a moron. I'd also be trying something more innovative in cinematography -- ER introduced Steadicam shots to broad dramatic series work, this preview and the behind the scenes together look like typical direction and DP work for today.
