So nothing should ever be a challenge, Bond should just sit in a car with Star Trek tech and take everything out with missiles and nothing he does should in any way be based on real world science? I am guessing Die another Day is your favorite Bond film.
If the gadgets do all the work then why does MI6 even need Bond? They could grab any person off of the street and they would do just as good a job.
Oh and a radio that small with a battery that lasts, transmits as far as it was show and doesn't get detected when the bad guys search Bond, that is pretty high tech. It may not be out of Star trek but it is beyond anything that you can buy right now and it would take a pretty smart person to buy it. Also a gun that can only be fired by the person who owns it. Again that seems pretty cool and high tech to me and it has the bonus of feeling like something that could exist in the gritty world Bond is a part of, so they were perfect examples of Bond gadgets. Just because they didn't transport him to Mars doesn't mean they were not high tech.
I think the films really lose something when they get away from the character as it worked in the books so I am glad that after decades of the films going sci-fi that they are getting back to the spirit of the books and putting Bond back in character.
Oh and the old movies featured long pan over locations and at the time they were made those were considered artistic shots so I don't see how you can say there is anything wrong with Skyfall having artistic shots in it. There is no reason why you can't combine art and action and that is one of the reasons I love Skyfall is that it does this. Most film makers give up trying to make a film look good once they start making an action film I am glad that wasn't the case with Skyfall.
Oh and there is no way to fit a rocket inside a car and in this day and age most people watching know that so unless you are making a comedy that is not going to happen in a modern film. Now a days if a film starts out gritty people get take out of the story if it then features some sort of magic CGI tech that seems out of place in the film's world. That is the biggest complaint I hear about the Nolan Batman movies, that they seem to take place in the real world but then some of the gadgets seem to be magic. So You can't blame Bond for avoiding that pitfall.
