You know for all its faults that episode has at least two things going for it--it's fun, and the characters are all in characterMy favorite part is how well the remote control for Spock's body worked. Not only moving the legs, but keeping his torso up and all those stabilizer muscles needed and all seemingly with two joy sticks and some dials. That McCoy, he knows his stuff.
(Now don't get me started on out of character moments in The Way to Eden)
