i can not understand why so many people do not like this film . robert de niro be on top of his game and deliver his line with such aplomb and one have to believe this be his everyday demeanor . grant and the film seem to take on many buddy film convention while try to make fun of the concept and it go without say this film be genuinely funny . from the police dog and to the fact eddie murphy do not annoy the heck out of me and this film be a real keeper . rene russo also even out the rest of the cast perfectly and establish her role so it do not interfere with the bud relationship between de niro and murphy .
