I never got onboard the "Sabine is a Mary Sue" train but jeez, when Ezra exclaimed "they're in trouble" when she charged alone at like 5-6 stormtroopers, it was a bit too much.
You know, I gotta agree. I've always been annoyed at the "Sabine is a Mary Sue" sentiment, but I could actually see it in this episode.
In this same episode, two Jedi go up against a single Destroyer droid and like 4 **** droids and it's treated like they can't handle it, but Sabine goes up against 6 specialist stormtroopers and they're just like "She's got that, we don't need to do anything else."
