It’s always been a fairly reliable bet that medical dramas will go over well with audiences. So an action-packed series about a team of paramedics and their helicopter support staff should be a slam-dunk. The problem with Trauma, which only made it to one series before NBC gave it the axe, is that it lacks the substance of classic shows like E.R., or the human touch that has made the likes of Grey’s Anatomy so popular. The characters are one-dimensional, and their relationships never get any deeper than the impressions given to viewers during the first episode. There’s a whole heap of action, much of it brilliantly choreographed, but supporting characters are never anything more than instantly identifiable stereotypes. After a few episodes, it becomes immediately apparent which actors are about to suffer some form of horrendous (and usually far-fetched) accident, and the heavy use of cookie-cutter storylines makes any semblance of drama or tension impossible to maintain.
