Yeah, Blind Staffsman Donniei-chi and Captain Aimbot were a little overdone for the Chinese audience, but I get past it. I mean, it's Star Wars. They took down Imperial walkers with tripwires and rolling log traps. One would assume that the Hoth walker commanders could, you know, just stop walking. If one or two silly action scenes is the balance between good and bad, all of these movies are in the red. They definitely should have staged that Donnie Yen scene in some kind of terrain where being able to engage a half dozen stormtroopers in hand to hand combat made sense, but oh well.
Where Rogue One wins me over is in the way it engaged me from start to finish. Even if I kinda rolled my eyes at that one scene, I still cared about what was happening when the next scene rolled.
Can't really see where the FO troopers are much better though. I mean, Corporal Beatstick has a gun, and chooses to pull out his energized stick... for reasons. And the argument that the original stormtroopers weren't just as, if not more, merciless is ridiculous. George Lucas just didn't feel the need to show it onscreen, but the original film shows two separate atrocities against civilians in it.
They didn't slaughter themselves...
You're reaching way, way far into dark, dark places on this "FO Stormtroopers are harder" argument. They're nothing more than re-skinned OT stormtroopers with electro-beatsticks. Giving one of them a flamethrower doesn't make them any less of cannon fodder. They didn't win a single battle, and didn't kill anyone on Planet Death Star either.
