A lot of people might look at the IMDb rating of this movie and avoid like the "Killer Tomatoes"... That would be a mistake. "Mr. Nice Guy" has both humor AND drama, a great combination during a time when a lot of the movies being made concentrated too hard on one or the other.
Yes, it was a relatively low-budget movie, but acting (and a great comedic script!) in fact took precedence over special effects, gruesome deaths, and "sex & Violence".
While the plot is relatively simple, it is a product that displays the movie-making formulas of the time and has enough plot twists to make it VERY watchable.
Even if you feel the rating might be too low to pop this one into your player, give it a try. You will not be disappointed. IMHO, at least.
