This is my sixth favorite episode of the show. The episode is ironic on two counts, since the show's creator Irwin Allen directed that film years later, as well as made the show "Land of the Giants".
Once again, the Lost trio are in another fun adventure, as we see Robot is in biological mortal danger, Will and Smith are the doctors must help him by simply going inside the Robot. It's very interesting seeing both Smith and Will venture into Robot, which is pretty much a cybernetic funhouse just full of danger and a lot of neat things.
From Robot's version of white blood cells as there are these drones in him that patrol the interior of his body and neutralize foreign invaders. Down to the disorienting environment itself. The episode like a finely tuned body is finely balanced in all three aspects adventure, comedy, and drama. We see Doctor Smith in danger as usual but here this time he is in real mortal danger and it's suspenseful as we're hoping Will and even Robot will find a way to get him out of his sticky predicament. Even a really heart felt moment where we see Robot's heart is slowing down and Will is trying to physically keep it going it really shows how much he cares for Robot, but we even see Smith try as well though this act isn't so much his care for Robot (well a little) but for Will himself.
This episode is not just a fun adventure but shows how far the friendship all three share for each other truly goes and the importance of having them around. Space truly would be a dull place without the Lost trio.
