No spoilers, just some quick comments.
It isn't bad, but it isn't great, either. Good enough is where I'd put it. Of the Daniel Craig Bond moves, I'd rank this one as #4 (of 4).
A couple of things that stick out at me were the early car chase scene. WTF people? Who wrote this? It wasn't so much a car chase as "lets watch expensive cars tool around Rome". No shooting, nothing exciting. Just what looked like an orange Lamborghini chasing whatever custom car Bond was driving. (Okay, it was a custom Jaguar C-X75 chasing a custom Aston-Martin DB10.)
See, Bond was driving a bullet-proof, armored car. WTF was he fleeing from? The bad guy couldn't get to him. He could've come to a complete stop, let the guy roll up, wave, and ask him to do his window and it wouldn't have mattered.
The second scene that bothered me was the train fight scene. Holy fuck! Are there no other people on the train? The bash their way through like 4 or 5 cars on a 7 car train and there aren't people scrambling to get out of the way. No staff, no passengers, nothing. It was like a ghost train. Then they get off at the next stop looking freshly showered and pressed, not like both protagonists just got their asses kicked and should be covered in bruises and welts and walking with severe limps.
The final scene that irked me was where Bond was chasing the cars in Austria with the plane. The plane loses its wings and a strut, then slides down the mountain only to bash through a barn and smash into one of the bad guys cars. And NO ONE IS OUTSIDE TO SEE IT! It is like they found the only Austrian ski resort village that IS TOTALLY DEVOID OF PEOPLE.
I guess they smashed up so many cars they had to save money somewhere, and skimped on the extras (except for the opening scene in Mexico City).
A little long, and a little disjoint. It really helped that I was at an Alamo Draft House and ordered a couple of beers while watching it.
All in all it really reminded me of a Roger Moore Bond as opposed to a Daniel Craig Bond. Not Moonraker bad, but still...
