The problem with remaking films from the 80s and early 90s
This isn't the 80s/early 90s anymore. Not only has filmmaking somewhat changed, but audiences have changed.
Back then, action movies could have a two hour movie filled with shootouts and explosions, and car chases every ten minutes or so. And you didn't even need much of a plot to link together much of action.
The original RoboCop was definitely a product of it's time, as is the remake. The new movie takes a lot of the social issues we have today and uses the ones relevant to a "police officer gets brought back to life to become a cyborg cop" movie today. The original kind of glossed over or didn't address issues that the new movie tried to explore. While I was initially turned off by the focus on Murphy's family post-op, that's something that a film these days would delve into, if for any other reason than that audiences would expect something like that.
While I beleive that the action sequences needed to be better, I think this is probably one of the remakes out there. Total Recall, while having some amazing and imaginative action sequences, fell short on taking it's basic premise of "implanted memories" and figuring out what is real and what's not.
I think RoboCop gets to much flak for not being an exact duplicate of the original when films like the Psycho remake and even Watchmen, both which are shot for shot remakes, garnered a lot of hate.

Don't forget: It's just a story being told
