Campy is good when it's done well. "Total Recall" is a classic to me, and I don't think it's a movie that can be done well. What's more Arnie was integral to the success of that movie, I seem to remember from the special features on the DVD version of it that I have sitting around that the movie almost died, and he had a lot of influance on both keeping it alive and adding elements to it that made it what it was. Things like a few of the exterior scenes so people could get an idea of what the world this was taking place in was like did a lot to help convey the movie, and were his idea. I think people seriously underestimate how talented everyone's favorite muscleman is, even the famous cheez he spouts seems to involve a bit more thought than people think whn you hear about some of the movies from behind the scenes.
As far as the issue of things being recycled, well I think a lot of it has to do with Generation X being "The Lost Generation", we were pretty much skipped over by society and wound up creating very little of our own, or seeing very little created to be targeted at us since we've never been a very profitable demographic compared to our parents (the boomers) or our successors (Generation Y which is starting to arrive). A lot has been written about the subject. The bottom line is that us "Xers" are pretty much adults now and we have untapped money even if it's not as much as previous generations, and really to get to that vein of cash childhood or teen nostolgia is pretty much the only thing we have to target given the fact that we have really gone nowhere and produced very little since we never moved into the jobs of our parents due to modern lifespans and various sociological realities keeping them in those same jobs at the same time they would normally have been phasing themselves out.
