Yeah, I had issues with Miranda's Romance.
I like how she wanted to do things for her own. She's independent and realizes that Shep has cures to find (Nope! Totally not for the Assassin though!

') and peace to make, even if Shep already has five million less important tasks. Her independence and strong character is what attracted me to her.
But, at the same time, She needed to be there more simply because she is still an LI.
And, her romance scene, I liked it, because I thought their little banter was cute, but I would have liked taking her and Orianna onto the ship after saving them and having a more traditional Mass Effect romance scene on the way to Earth like the regular squadmate romances, maybe even one to rival Liara and her...romance scene.
It also would have been nice to actually talk to Ori for once, since she is Miri's sister.
