Sorry but I found it really disappointing. I know they wanted it to be a "send off" sort of film but its just missing the old bond magic. Its gone too far with the gritty and lost the charm. There was no fun anywhere its depressing from start to end with bond being miserable throughout.
I know others will say its ties up the plot points from the previous movies, but the fact is there were no points to tie up until they made them. That had already been done, what we have here is another director tacking onto the back on previous plot lines instead of coming up with something of their own.
Bring back the proper unsympathetic Bond villains with a secret lair in a volcano or a floating city and a private army of evil henchmen. Put some dodgy jokes back in, and stop trying to be hip and edgy :(
