I would have absolutely preferred playing Shaundi (who isn't any less smart by the way, its just about their personality). I'm not too much of a fan of Kinsie (she conflicts with how I view my boss and her supposed superior intelligence is unfounded and annoyingly displayed). But Shaundi's an intelligent badass, why not play as her? I don't mind too much, because the both Shaundi and the boss were portrayed nicely enough.
The boss appearing at the end completely fine, as if it was nothing
"Op I'm in hell? Alright Ill just chill."
And how Shaundi just did other things while Kinsie and Gat messed around in hell, which I don't think of as not caring, but just considering it business as usual, not a big deal, its not like this is the most dangerous thing they've done.
I still hate Saints Row 4's dlc (its just, gaaaaah). But I hope to get into the expansion.
