I'm sure it's already been said, but I just have to put my 2 cents in.
The only reason why Robocop is considered a classic is not because it was an action film but because it was a satire.
I saw Robocop on a free pre-release screening in college in 1986(?). I thought it was going to be some standard Sci-Fi action B-movie. And, had that been the case, nobody today would have even remembered the film ever existed. It was a pointed black comedy that was unlike anything else we'd seen before - not for the effects (which were on par with effects of the era), but for the subtext.
Robocop (not unlike like, Fight Club) was frequently misunderstood by viewers and many film critics who thought the violence was more exploitative than necessary ... which was missing the point entirely.
In fact, the funniest thing about Robocop was that, as we laugh at the comical excess of violence, we are actually participating in the film's thesis about dehumanization of violence in social media .... i.e. we, the viewers, are actually a part of the film's ultimate joke. Unfortunately, not everyone "got it." Robocop is a black comedy.
You can't reboot satire in the same way that you can't update an old joke... because it's been told before.
But in the typical Hollywood fashion (a la Total Recall) the purpose of funding a "reboot" is simply to cannibalize the name of a known commodity in order to augment the marketing of an otherwise typical Hollywood special-effects "blockbuster." It's nearly impossible to sincerely reboot a film that is, at it's core, a social and political satire specific to one time in US History (arguably some remains relevant today, but the distinct corporate setting was really reflective of that time in the 80's when films like Wall Street were also set).
It's conceivable that an insightful writer might use the Robocop platform for an updated modern social and political commentary, but we all know that's not likely going to be the case with this "reboot" borne in an era full of "reboots.
This new film is just going to be an effects extravaganza with the name "Robocop" attached to it, that's all. I predict that thirty years from now people will still remember Robocop (and Total Recall) as Verhoeven films. I think the reboots will be eventually forgotten.
FWIW I haven't read anything about the upcoming film (but I will) so this post is a knee-jerk reaction to the knowledge that a reboot is happening. I'm 99% certain I'm right.
