Rushed ending. For the first half of the film they set up the circumstances of how Alex Murphy became Robocop, and it's rather well done too. With the assistance of Samuel L. Jackson's character it's described how, in the world in which Robocop is set, robots are banned within the USA's borders, and therefore the idea of Robocop is born. A human inside a robot. It's done fairly well, although perhaps more emotion form Kinnaman and Cornish would have helped.
There's then the amount of "badies". There's three main foes which Robocop faces, but so little links the three of them. In fact, there's only a link between two of them and the third only becomes a foe in the closing of the film. You have the feeling that the writers lacked the imagination to create a strong foe, or even a plot connecting those foes.
Comparisons of the original are easy to make, but dangerous too; it's a different film. For example, this Robocop is more athletic. The original had stronger foes, this film they're almost sidelined; an inconvenience to the plot of Robocop's creation. There was a sharpness with the ED-209s but in this film again they're like an after thought. In this film the ED-209 battle was rushed to the point where it's just machines fighting machines in a blur of special effects. That fight is rushed so that finally Robocop could face his final foe in what really was an anticlimax against Michael Keaton, who's character has absolutely no menace to him at all.
Gary Oldman plays Dr Dennott Norton and when you look back it could almost be described as a film about his character. How he created Robocop, and his regrets when his boss changes direction of the Robocop program. Certainly himself and Jackson are the stars in this film.
Ultimately the third part of Robocop feels rushed and weak. Overall it lacks the wit, sharpness and intelligence of the original, but Oldman's character added a more human element. Ignoring the original film, it's really a lack of a strong intelligent plot and rushed end which takes from what could have been an 8* film to 6*.
