Audio problem: The little RC claw thing that 790 takes control of starts following Xev and Stanley around as they carry his head. In most shots when it's seen moving it has the loud electronic engines moving it's wheels and a bell sound heard. However when they are going down a hall holding 790 up to several control panels and he's telling them access denied, it is still following them on screen but is completely quiet. (00:53:15)
Audio problem: Right after the Cluster Lizard gets into where Xev is being held to change her body and mind and eats the 790 Unit, it cuts back to Stanley walking. Two larger robots come towards him and he swerves to avoid them, while you can hear their loud clunky footsteps. However the sounds of their steps do not match up with when they are stepping. (00:41:25)
Audio problem: As Stanley is running towards the correction facility to not be late, there are several shots of the clock on the wall with the green bars ticking down. There is an audible tick every time a bar counts off. In one shot, we see it count down to having just 2 bars left, but it cuts back to Stanley running and we hear 3 clicks. When it cuts back to the clock there are still 2 bars left. Also in an earlier shot when the clock is off screen we hear more clicks than we see of bars having vanished when it cuts back to the clock. (00:34:00)
Audio problem: As Kai is the last fighter left, he flies towards His Shadow's control pod on his ship to ram into it kamikaze style. As he's approaching and it cuts to the control pod dome starting to close, you suddenly begin to hear the alarms going off inside The Fore Shadow ship. And it's heard from inside Kai's fighter, and from outside from camera angles. And then when Kai crashes into it and flips out inside, you still hear the alarm inside the ship at almost the exact same volume as heard from outside. It's almost quieter even. (00:03:50)
Audio problem: As the Fore Shadow is charging up its blast each time, when first shown it makes a high pitched shrieking sound as the energy spreads across The Web of cables fanning out from it. However as the battle continues, this sound effect becomes very inconsistent when it plays in correlation to the energy blasts charging up on the ship. (00:02:15 - 00:03:20)
Answer: From what I'm seeing, the answer seems simple. The robotic heads allow the control of the body they need. However, no mater how advanced you make a robot's body, it will never quite be as flexible and versatile in it's movements and actions as a flesh and blood human body can be in most cases. And if they do put the effort into creating a robotic body with the capabilities they need, and be durable enough to last... it would cost a lot of money. The Cluster has a large influx of constant prisoners that they use for feeding the Lexx and other needs, so human bodies are easy to come by and in vast quantities. Them simply producing robotic heads with the ability to interface with the human nervous system and placing them on the decapitated bodies of expendable prisoners is a hell of a lot more cost effective and easier to do with the technology they have. It's just a cheaper, more effective option for them to have thousands fo 790 Units in production and use without the cost of manufacturing a fully functional and durable robotic body for them.
