I don't think the characters are boneheaded (not most of the time, anyway), but I do feel like the story is misusing them really badly by now. They've become too one dimensional, losing whatever nuance they started with in favor of rehashing the same material over and over again.
Eva was clearly in a rut and rather than force the characters to evolve, she's brought in new characters (like Gillian or Jack) to put a fresh coat of paint on the same scenarios. I was hoping for more.
Err, no. 30.1 squared is 906.
01. The square root of 906.1 would be slightly more than 30.1. A very important distinction, as I'm sure we can all agree.
