The actors are able to convince the audience that they truly cannot see these aliens who are controlling their lives and observing everything that they do. This is important, because if the people knew they were constantly being watched, that would defeat the purpose of the whole play, which is to put middle class America in a fishbowl and observe it as a child looking at a goldfish would. As for the actual production of the play, everything adds nicely to the feel of the performance. Props are moved on and off the stage by the aliens, further endorsing the notion that we are not in control of our own lives. The actual props themselves seem to recall an older way of life, such as the Formica topped tables that likely gave the play its name.
Music is piped in before or after a scene occasionally to set the mood, which is a nice touch.
Even a few of the characters start to sing, which leads to an impressive part near the end where several of the characters launch into soliloquies at the same exact time, which can be extremely difficult, as anyone who has tried to have a conversation with someone who just won t shut up knows.
