I'm so tired of people thinking this movie is like Rambo 2 or 3 ;_;

Well you could see why they would think that. After Parts II and III came out the character became synonymous with over the top action, high death counts and explosions that a lot of people forgot that the series started out as a very grounded and gritty war drama/action film. Either that or they never saw the original and just saw Parts II and III when Rambo started gaining mainstream appeal.
