To play Devil's Advocate, I did enjoy that Disney wasnt shying away and pretending the rebellion didnt have to do morally gray (and even leaning on black) things to get the upperhand. In true conflicts like these, even the "good guys" need to do bad things. The opening of Rogue One literally had our "hero rebel" silencing an ally of theirs that was too fatty to get away...both to spare him the torture and possible arrest/execution from the empire and to keep his mouth shut over what he knew.
It also helped to show that the rebellion wasnt this centralized group entirely, there were "members" of them that went into extremist routes like Saw Gerrera...sure, he was going against the empire too but his methods were far too extreme for the rebellion to "officially" accept him...but lets face it, Im sure the higher ups were glad that someone was doing the harder choices so they wouldnt have to do it themselves.
The rebels ARE the good guys but to fight an enemy with no morals, standards or lines they wont cross, its difficult to get the upper hand without having to let go of some moral and standards yourself. So I "applaud" Disney for not shying away from the grim reality of what is being in an actual rebellion.
