Will is by far the most accomplished of the group. His films have everything - originality, strong visuals, beginning-middle-end plotting, humor, charm. Some of the younger directors (Zach, Adam) seem too derivative, don't work as well with their actors, and the pacing feels a little off, like their films are always too long or too short for the idea.
Least favorite - Jessica - I pity whoever spent the 50k/yr or so it takes to send someone to NYU film school. This is the best she can do?
