SPOILERS BELOW !
You do realize that in that god-awful movie, the main bad guy your groomed into being wary of, the gruff irish hitman sent to kill the brothers turns out to be ... DUH DUH DUH ... THEIR LONG LOST FATHER !!! OMFG !!!
That seriously had to be the lamest, most ridiculous, and most unnecessary "twist" anyone ever tried to pass without at least a smidge of irony. Then he completely changes his ways and he's a good guy fighting with his sons. That's just retarded.
Maybe in the sequel their long lost Maa joins the crime-fighting team !
SPOILERS OVER.
