The film gets 3/5. The Gal Who Got Rattled gets 11/5. So, overall, 3.5/5.
Every time I was getting into Rogue One, there was some seriously awkward dialogue, or some cameo shoehorned in, which took me right out of it.
Also, there's some seriously bad plotting, including (but not limited to) plugging in a really long chord, realigning a satellite dish and finding a file in a really big tower of files.
