Turning the marauders into rebels was a bit cheesy, or maybe just lazy writing.
I thought that too on my first viewing (in cinema). On my second viewing (at home on BD) I didn’t mind it. Not yet sure if my opinion actually changed or if having a few months for the film to sink in just desensitized me to the idea.
After all, I wasn’t completely yanked out of the film and repulsed when you-know-who showed up this time either. I still think it’s a horrendously stupid cameo and I hate the very idea of it, but it didn’t totally destroy my overall viewing experience like it did the first time…
