What makes the original Rambo movie so good is that it's about a bunch of incompetent small town cops fucking around and finding out.
Corrupt cops in a modern action movies are the exception, the bad apple, the disgrace to the badge that the good cops inevitably bring to justice.
In Rambo they are portrayed like the petty tyrants they so often are. There's even one copy who voices objections to the flagrant abuses of power, only to be shut down by all the rest. Much more true to life.
