First 40 minutes quite good; then, it became silly. [Do not continue to read if you want to see this movie and do not want to know what happens---SPOILER ALERT]. First, why didn't Bond just shoot Silva in the tube when he was on the ladder? Why talk at that point? Silly.
And why wasn't an SAS squad flown into the Skyfall estate to help with defense? Again, silly stuff spoiled it for me.
and why didn’t the girl take out the Muzzie on the train with a SECOND shot?
Otherwise, I thoroughly enjoyed it.
