Kaylon's
Spoiler: Don't read any further if you've not seen the episode. This is more a bitch post. So don't read if you've not seen it.
So... this all powerful race of androids have studied humans and other life forms in order to decide on if they should join the union.... Then they decide to set out to destroy all intelligent bio-beings because, well, at some point in their pasts they had slavery...
So... they head for Earth first... and are winning the fight, until Isaac says he will use... Da da! EMP to stop all the Kaylons on the ship!
Really?
Can you tell me, if these androids are so advanced... why the hell didn't they figure out how to keep an EMP from shutting them down? You'd think a Faraday Cage placed inside their bodies would prevent that! But no.... No... They were just too smart for their own metallic butts! Oh... and the race that built the Kaylons... stupid. Just plain dumb. All they needed to do was drop a few EMP bombs. Problem solved!
