On the technical side, “Lovesick” is a very well-constructed production, from the writing to the directing to the acting. The transitions between different scenes and characters are fluid, the multimedia works to add humor, depth, a sense of place and interest to the story, and the story itself functions well on a number of different levels. At its heart, “Lovesick” is sincere, clever and profound, alternating nimbly between lighter and more challenging material. Compelling and moving through and through.
