OK I will take time to make a larger post this time and not just my usual comment.
Actually, for me this was one of the more enjoyable episodes of this season, but still sucking at many points and not being scifi at all, not even soft scifi (then again there wasn't real pure sci-fi apparently apart from literature and I have trouble with concentration when reading books, unles it is something I am really interested in or well I didn't really read scifi literature except few exceptions and didn't finish reading them). But for action episode, this one was better for me than last, I didn't like Simeon's interaction and the way character was handled around and what made this episode's point. Greer acted like asshole at some parts btw, that was not mentioned by some people here, he is not as good man as some people tend to make him and he certainly got creepy at one moment. Rush motivation was more believable in this episode and he was actually less of a villain (pointing that to atlantisforlife's comment based on other people comments). The moment when Greer got shot was also largely Greer's own fault and stupidity, he just stood there still for like minute turned behind.
Rush in the end could have finished Simeon saying what he wanted to say, just to be sure he didn't really have the information when it was clear he wouldn't be able to kill him anyway, I mean this scene was very 24 like, like when Jack kills Nina in third season, although that scene was more believable and Rush didn't say anything during this scene unlike the similar scene in 24.
But I liked the way Rush handled the situation in the end and being smart, also the way he lured Simeon. Also he didn't really lie, he only just found out about that he could trace him or whatever was that, but when he stood up before and didn't get shot he was sure that Simeon wasn't in his place anymore, before he was able to fully reprogramm it or check, whatever. So he actually did put that into risc, it wasn't only the trace he later picked up. But whatever, that scene was overall confusing and could be intrepreted in many ways and the acting of Scott was terrible as usual.
Eli is very poorly acted during this episode as it was already mentioned and it wasn't much remarkable.
And of course the minde disabling part was a bit contrived as well, first he says sorry that he isn't able to defuse this apparently timed bomb and have only some seconds left, then he remembers he has that wire in his glasses and uses it to enter the tiny pin, which he wasn't able to get in before and get off the cover and do stuff. I don't get the proximity part either, but it was clear that if she moved it would set off or maybe if there was fast movement around which there wasn't, but still it doesn't make much sense. Also it was LA explosive, not earth made.
But overall, if you look past all the nonsenses, I actually enjoyed this episode for being bit more fresh.
EDIT: Mind you, I wrote this post only after partially reading first page of comments.
