The interactive element in the second half, with the audience interrogating suspects to determine the murderer.
What I didn't like
The sit-com humor in the first half and the fact that, except for wearing fangs, the characters did not come across much like vampires.
My overall impression
It is a novel idea: Boston Bar Bloodsuckers turns the characters from TV’s Cheers into vampires and transforms the situation comedy into an interactive murder-mystery.
