A few points:
It looks good on a big screen, but it does not look amazing. I was expecting amazing.
It starts off slowly. It has a story to tell and is in no rush to tell it – it clocks in at just under 3 hours. This is pitched as sci-fi blockbuster but is more space opera. There’s nothing wrong with that but I went in having purposefully avoided seeing trailers or reading anything about the film and I did not get what I was expecting.
The sound sometimes overpowers some of the dialogue. I thought it might be just my screening but it appears that others had the same problem. I also felt that the soundtrack was trying too hard to manipulate your emotions.
Apart from that, I left the cinema thinking it was a good film and I enjoyed the story even if I did not totally understand it.
