Also, this is probably more a personal thing, but some of the writing with Miranda seems a little weak. I mean, the first encounter was really good, but the other stuff feels a bit flat, with some lame dialogue.
And I feel perhaps they missed a bigger opportunity with the whole 'femme fatale' idea they had originally imagined for her in ME2. I mean, I guess it depends on what happened at the end of ME2, but they probably could've played up whether you can trust her or not.
Then again, I don't know what she's done with those Alliance resources...
