read it a few more times as you get older, gWIL...by the way, that's not a slam on your age or anything, please don't take it as so...I found myself enjoying and understanding exactly what Heinlein was going for with this book the older I got.
It was depressing to not get the powersuits, however...Heinlein devoted entire chapters explaining the suits and the movie just totally blows them off...but of course, if they had the suits, we wouldn't see all the beautiful young actors!
