I get the plot reason for it. It’s just that it’s a couple more coincidences to add to the pile in a movie that has so many coincidences.
It’s hard to describe, but I didn’t really like the “set up” of having spies there. Also, for many reasons I won’t get into here, the Maz sequence just kinda took me out of the movie for a while. Pacing is one of them.
Again, let me just say, these are minor points. Overall, I think it’s a VERY good movie, but one that has some big problems. I’ve only seen it once but I’m dying to see it again (seeing it in a couple days). Absolutely can’t wait for it to come out on blu ray, and for Episode VIII.
