While the plot to Vital Signs is fairly simple, it did keep me engaged the whole way through. The cast of characters, and their interplay, is what really held this serial together.

The acting is top-notch, with Nicolas Briggs giving another great Doctor-esq performance.

Like the previous The Wanderer release, the real downside to this serial is that sounds mixing is all over the place. I had trouble hearing some of the performances due to such quiet mixing, while other actors in the same scene were too loud. The music sometimes drowned out the vocals too.
