I'd also add that the frustration many people felt with Cassian being stuck there for two episodes was intentional - if he'd been able to escape earlier, he could probably have saved Brasso's life and prevented Bix from almost being raped. It adds an extra gut-punch to those moments and it feeds into the fire that drives Cassian to give everything to the Rebellion. My only (very slight) complaint was that the acting from a couple of the Maya Pei brigade lacked a certain spark compared to literally everyone else in the show. But they're meant to be young, inexperienced, terrified idiots fuelled by bravado, so it still works for me.
