Land of the Giants: "Genius at Work": Cute idea to let the main actors play at being giants for a change, and at least this time they remembered not to have the clothes change size like they did with Linden Chiles many episodes back. I wish that episode had come after this one, though; if the giants already had a shrinking formula, it makes Opie's growth formula and antidote seem like less of a breakthrough. Although it's quite a convenient happenstance that the amount by which the formula enlarges people (and dogs) just happens to be the exact 12:1 ratio that will put them on the same scale as the giants. What if they'd come out only half the size of a giant? Or twice the size? What would happen if a giant took this formula?
In the final act, when the gang was at the bad guy's farmhouse and Fitzhugh told Barry to run to the university and get Jody to call the police, it took exactly 2 minutes and 1 second after that for the sirens to sound. Even if the farmhouse had been right next door to the university and the police station, it should've taken much longer than that.
The Time Tunnel: "The Walls of Jericho": Good grief, this is a surprisingly blatant exercise in religious piety. "We come from a time when your God is our God." Everyone but Ann being a Biblical scholar and gazing on in awe as "sacred history" unfolds, exactly and literally as the Bible states (even though real archaeology has found essentially nothing to corroborate the Biblical account). The Israelites and believers in their God being unequivocally good and the pagans of Jericho being totally evil and deserving of their fate. It's like one of those freaky Archie comics Al Hartley wrote as Christian propaganda tracts. Heck, it establishes that Tony and Doug were actually mentioned in the Bible itself!
Well, at least the writer's piety means that, for once, there are very few liberties taken with the text the episode is based on, although it is an ahistorical text. It had to embellish Joshua 6 a lot to fill out the episode, like giving Rahab a traitorous servant, saying one of the spies was captured, and inventing an apparently imaginary pagan deity demanding human sacrifice as the justification for Jericho's destruction (the Canaanites had dozens of gods, but none named "Kimosh" or whatever as far as I can tell). The Bible basically just says that God just arbitrarily gave Jericho to the Israelites, not for any particular reason except as a gift to his favored people. One surprise is that the episode acknowledged and used the Biblical description of Rahab as a "harlot" -- I guess the normal reluctance to acknowledge the existence of that profession on TV was overridden by the fact that it was in the Bible.
It did take a few liberties with the Biblical text, though. Tony claimed the Bible mentioned a red sash as the signal to spare Rahab's home, but there's nothing like that in Joshua 6. Also, the chapter does say that Joshua ordered the two spies -- Tony and Doug in this version -- to go in to Rahab's house, bring out her family, and escort them out to near the Israelites' camp. So I guess Ann the skeptic can take some comfort in not every word of the text being literally true -- but either Tony's memory about the red sash is wrong, or the Bible in the TT-verse is a bit different.
Several Trek guests in this one -- Rhodes Reason, Arnold Moss, Abraham Sofaer. And a Batman guess, Myrna Fahey (False Face's moll Blaze), as Rahab. I was impressed by her in both roles.
In first run, this episode was largely pre-empted by news updates, because it aired on the night of the tragic Apollo 1 fire that killed Gus Grissom, Ed White, and Roger Chaffee.
