BioWare deserves praise for so many different mission types, but this is a bit of a swing and a miss. Storywise it's as nuanced as any, but flip-flops a little. Playing as a Renegade is typically thought of as the canon choice, as sticking to pure Paragon forces the soulful Thane to become bad cop in an interrogation scene.
That scene in and of itself is inventive, but Thane's mission feels like different bits stuck together. It does what it's supposed to, but it's a stark contrast between the deep delves of some of the others featured here.
It's also entirely non-combat. While that isn't a deal breaker (with another non-combat mission appearing much higher), it feels like a waste of Thane Krios' reputation as a master assassin. That plus the catwalk sections can be frustratingly fiddly, making you wish you could pull your gun out and start blasting.
While it's certainly heartfelt to see Thane and his son Kolyat work through their differences, we know so little about their species, the Drell. Those two are the only ones you meet outside of DLC, so you'd think BioWare might've done better letting us explore this angle rather than another redemption arc.
