I liked Miranda a lot too. I'll be honest, because she's modelled upon Yvonne Strahotski she is obviously going to be hot, but she to me combines strength with vulnerability. She's... human. Genetically she may be 'perfect' but she has doubts and insecurities that she has walled up around her. It was also fun for my Shepherd to systematically break them down with a sledgehammer too.
i was entirely opposed to her at first, and then slowly started to like her character a lot. she's awesome. i love how her loyalty slowly shifts from cerberus to shepard. it speaks levels about her.
It does, I think it also speaks levels about Shepherd too. For good or ill, Shepherd is incredibly charismatic. I think it blew TIM out of the water that in a relatively short period of time, he managed to convert two of his best agents (romancing Ms. Lawson in the process), garned complete control of a multi-billion dollar credit super-frigate and converted it's entire crew compliment (Not a single case of someone attempting to prevent his mutiny).
I would think that TIM should of been a bit more careful, because Shepherd did the same with both the council and the system's alliance two years beforehand!
