I actually thought Cushing was a lookalike actor with a voiceover - I walked out and said to my wife that I thought they got the casting perfect
Loved the film. It's got an Empire Strikes Back vibe to it for me. Not quite up there in terms of quality obviously, but definitely in tone. It's good to see "normal" people instead of always having the high profile rebel heroes at the big flashpoint moments like in the original trilogy. +1 for OH MY GOD VADER! I'm only sad the corridor wasn't longer

The music swelled just like John Williams' scores, but then always went the wrong way at the climax if you catch my drift. There was some good music in there, and I do like Michael Giacchino usually, but it was nowhere near as satisfying for me as the main scores.
That's about it, I was happy with everything else.
