Great ending, not as many 007 one liners but that's ok, some very interesting camera angles. My personal favourite is the opening walk scene when he fires the bullet. It's used again in the end of the movie but with a much different approach, very clever.
I'd say there could have been more to Rami Maleks villain except the few scenes he is in. Would be interested to see the deleted scenes that weren't used.
At 2.5hrs it's a must watch if you want to say goodbye to Daniel Craig
