From www.whatculture.com:
"Action films are a dime a dozen and a lot of them feel like the same old story - a man with a dark past loses someone and they use their skills to gain revenge. Unsurprisingly, a significant amount of these movies are forgotten about, forever destined to miss out on the credit they sorely deserve.
Some action movies do break the mould but are hamstrung by poor marketing that does little to differentiate them from more generic offerings. Simply put, a lot of trailers focus on the tried and tested plot points that make action movies generic and amorphous with one another. As a result, the action films that do deviate from the formulaic are sometimes overlooked.
Whether it is because of bad marketing, an uninspired cast or deeper turbulence, all of the action films on this list never got the attention they truly deserved. These films showcase that revenge is a dish that can be served in multiple ways and can still lead to exciting results."
