If it's crap ... We'll tell you
Hey guys I myself have seen the first two modern Bond films but my parents haven't do they need to to understand Skyfall?
Asking this question it would appear that either your parents are in their 90's or YOU seem to think they are?
Watching solace without seeing casino first might be a slight problem but only slight as it starts pretty much where casino ends (shooting Mr Whit then bundling him into the boot for interogation) but skyfall is a film that stands on its own not as a continuation of them (like most bond films are)
I'm sure your parents aren't that old so are you worried they wont understand the computer hacking and releasing of information part of it (are they technophobes?) The whole premise has been called anti-wikileaks which any self respecting person who watches the news should be aware of.
So I'd say give your parents more credit than you do (unless they are brother and sister and live in a trailer home which means you probably don't have thumbs and more than likey do have webbed feet)
i asked this question before i saw the film and didn't know whether or not it needed to see the first two in order to get this one as in if it brings up the first two
