Needed more kill variety imho but the ending didnt bother me like the rest of the folks here.
You know, like the opening credit scene was teasing the audience?
I expected way more clever, sneaky and accident kills than what we got. Even the "Accident Man" had more of these kills despite being a straight up beat-em up action movie. LAME!
Main killer basically shot everyone with a gun (or nailgun) with the exception of secretary and she basically begged him to make it look like an accident because she needed insurance money. Guess being in contract killing only pays off for the killers and the handlers. Secretary gets nothing for being in such a "high risk - high reward" business ROFL.
Him not killing the client made sense tho, it would raise too much of a fuss and someone wouldn't stop looking for the Killer. Besides, he didnt know his home address like the rest of the people he eliminated.
