9. The Expendables 3: The Blood And Guts Cut
The full version of the movie leaking online didn't exactly help the movie's chances of box office success, but that still doesn't change the fact that slapping The Expendables 3 with a PG-rating was the worst possible idea for a franchise that was based entirely on iconic action heroes mowing down rows of goons in gloriously violent fashion.
Almost as bad was the decision to sideline the majority of the movie's elder statesmen to focus on a roster of bland and forgettable new faces, which was presumably also done to try and market the geri-action ensemble to a younger demographic.
Trim out the vast majority of that storyline, throw some blood and guts into the mix, and The Expendables 3 would be a whole lot better as a result. The first two movies weren't averse to the use of some CGI-assisted crimson, and dramatically upping the ante in terms of violence would at least see the threequel deliver on the whole reason the franchise even existed in the first place.
