The other reviews have covered pretty much everything involving this episode, so I'll get right to it: I had previously stopped watching this show because it was getting dull. I saw that it was coming back to be the start of finishing up the season and since nothing else worth watching was on, I figured it could be worthwhile to watch again to see if things had improved (acting, etc.)
The crushing of Robocop Andy multiple times was good comic relief. And he was such a good sport about it too. Good times.
The episode itself was pretty formulaic right up until the ending when we are told that, until the satellite dish crushed Robocop, it was receiving data from...somewhere in space and something or someone was sending the signal. And that something/someone is heading straight for Eureka!
Speculation of what is coming to Earth was rampant here on TV.com and elsewhere. No one knows. This is what makes great TV - keep people hooked by not making it obvious as to what comes next and get them talking and guessing. I'm the Borgress, so what do I want? I want the Borg. In Eureka. Humans + Robocop Andy + Eureka vs. The Borg = Awesome. This is the Sci-Fi channel after all. ANYTHING can happen. Why are the people there stuck on the ground anyway? The intro. has buildings being lifted off the ground. Where's the episode where that actually happens? Exactly. It hasn't happened (yet). That is also a possibility for when "they" arrive at our little blue planet.
I also want to see Sheriff Carter randomly go postal on circuit boards and start laughing like a maniac. But that is another story for another time.
