I agree with Lanie.  Robert Dryden as a whacked out, high-jacking, cult leader who calls himself 'Reverend Joy' was great!  His references to marijuana - the focus of his religious movement - as 'God's herb' and 'our soul-food' had me laughing out loud.  You could tell that Robert Dryden was having a lot of fun with this character.  I listen to Mystery Theater on my MP3 player as I drift off to sleep at night.  'Sierra Alpha 638' is starting to grow on me.  All of the characters are great.  So is the dialogue.  4 stars out of 5 - Juror #4.
