First off, you're never going to improve on Paul Verhoeven's Robocop, which is just about the most spot-on, no-bullsh!t action satire you'll ever see. Unless MGM wants to hire someone like David Fincher or Brad Anderson, I don't have a very good vibe on a Robo-remake. And Red Dawn? Well ... obviously you'd have to update the villains, wouldn't you? Viewed through a socio-political spectrum, John Milius' Red Dawn might be one of the most "outdated" action movies at the video store. Plus, as cool as it looks on screen, the concept of paratroopers invading America is pretty damn hilarious.
So obviously I don't think much of either project at this point. (Sorry, but when I read the word "remake," my brain heads right to the word "lazy," although obviously that's not always the case.) But of course I'll see both of 'em as soon as they come out. I just can't help it. And since it's also an '80s-era MGM title that begins with a "R," I guess you can expect a remake of Road House soon enough.
