FemShep: "I'm just interested in...(sultry look) TALKING for a bit."
And any time Thane starts reciting his memories in present-time. First time it happened, I couldn't understand what's going on. Waited for Shepard to ask for clarification. Odd writing, didn't like.
Most cringe-worthy lines belong in romances. Apart from that, can't think of anything. Writing is top-notch. Loved that moment Tali recites poetry - and how it's interwoven with the ship accelerating. Loved every one of Harbinger's lines. "I am Harbinger. Face your annihilation." He's a good adversary, for someone with whom you have zero communication. "If I must tear you apart, Shepard, I will." - the phrasing here makes him sound almost reluctant.
Do we have a topic for the best lines? I loved that moment when Mordin cries, "What? Why?" He's almost as tough as Shepard when it comes to showing emotion. Good to see him emotional every once in a while. Fades quickly, that, though. Even that is in his character - or rather, species. Or when Tali says, "I'm scared, Shepard." And here I thought she didn't have a heart. Grunt's lines, "I get it. I thought you'd be glad." Don't have an option to be glad for him here, frustrating. the classic "in rides Shepard, securing victory through nuclear fire. I love that part. It has weight." TIM saying, "Miranda thought you'd be more resistant. She's not often wrong." Shepard's pep talk, "are you going to sit here, VORCHA?" EDI: I enjoy the sight of a human on his knees. She tells a joke! And it's such a powerful moment, because even amidst all this horror, it still works to relieve the tension, and because you don't fully know if she's serious or not. one of the best.
Well, love all of them! Writing in ME2 rocks. Best part of the game, really.
