Yep, pretty cringeworthy writing. Hopefully its not representative of the game itself.
Yeah, but Mass Effect had plenty of dialogue like that, even in stuff we all used to like.
"I will show you true power!"
"We will stop at nothing!"
"You were born to do this!"
"Go to hell!"
"Each of you needs to be willing to die! Anything less and you're already dead!"
I could roll my eyes at plenty of stuff from the series, especially some of those Renegade one-liners from the original ("I have nothing more to you." *pushes out window* "How about "goodbye"?").
I'm not expecting Shakespeare here. I'm expecting a solid, fun, and occasionally well-told sci fi story, on par with the original games (which had their own moments of both gravitas and ridiculous writing).
I know what level my expectations lie at.
