Eureka: Insane in the P-Brain — review
In general the ideas of Eureka aren’t particularly groundbreaking, borrowed from other science fiction shows they get away with it because Eureka is a character based show with the science making the mysteries but not the plot of each show.
In this episode I suspect they got the idea from an old episode of Star Trek where Ensign Row and Geordie were out of phase. Though this time is is Carter and the new head of Section five, a woman who has been working at SETI. Wandering around unable to interact with anything they must solve the problem before Henry turns off the device and traps them there permanently.
Having Henry become almost the villain simply because of how good he is at figuring these things out was great and I think this new woman on the show who is brilliant but tends to get herself in trouble with the things she says should be fun.
I had considerably more problem with the B. Plot. In this story Lexi is struggling with whether she should tell the father of her babies if she is pregnant. The problem with this is that I don’t think there should be any debate. It doesn’t matter if he loves her or if it will tie him down or any of the other things. He deserves to know he has children, with the only possible exception if he is abusive(or Darth Vader). I simply have trouble feeling any connection to a character who struggles with this decision.
Overall, the thing that most excited me about this show was the ongoing storyline that is in the background. If don’t right this could be a fascinating new chapter in Eureka.

While the science aspect of Eureka may not be original, the show tends to use things in a fun way. Though I agree that it is more about the characters.
I also agree that the story-line with Lexi is not good at all. Granted, I was never fond of her character. I just found her more annoying than anything.
The new woman could make things interesting.
