I Agree with much of what Russ has said about this episode. I enjoyed ti and yes it was comical in places. Sometimes it was comical in places where I don't think it was intended to be.  The first act was getting to a point of annoyance with teh repeating of teh phrase this alien kept saying. The closing line was comical and yet forced which perhaps made it even more comical. I rete is 3 out of 5 for good. Check it out
