THE ONE ULTIMATE PLOT HOLE

The Boss and Rabbi do have other bodyguards, such as the man on the balcony, the man Slevin mistakes for The Boss, the man on top of the elevator, the men out on the street when Slevin is brought in... and probably more we don't see individually.

Changing the town doesn't mean disappearing. He only changed the address, but he was available. However, if he stayed in the town, there was a danger that someone might see him with a boy.

1) Professional killers usually don't have to explain much. If he left town, it might have been for better job, for matter of security etc.

2) Both Boss and Rabbi, as we find out during movie, weren't often involved in violent or brutal activities. It has been said that killing Max, his family and Roth was made as a warning, a threatening example for others who might do the same. There is not much evidence of similar crimes afterwards. And as they were (almost) partners they didn't have to use killers for gang wars.

3) As we were told, only a short while ago Boss and Rabbi became hostile to each other. It is easy to imagine that Goodkat had something to do with it. Once whey Boss wants revenge, it is not illogical that he calls the last (or only) one that he ever hired for such a job.

Plus) Goodkat surely could have killed them at any time, but Slevin was the one who wanted revenge, and he wasn't a professional; while Goodkat was always welcome to Boss and Rabbi, he couldn't simply enter their offices with Slevin without causing some concern or suspicion.

Readng through many of the responses here. It is plain to see that people are too analytical, but at the same time, have absolutely NO clue what they're talking about.

1. "Why after 15 years..."

A. It was 20 years, and there is a widely known peace treaty between the two rivals. Bringing in some 'regular', would surely have the word out on the street; in no time. They needed someone they could trust, which is where Goodkat comes in. Its not hard to figure out at all!

2. How did they get to them so easily? ...easily? This probably took months if not years of planning. Goodkat was training 'Slevin' for years. Put it into perspective. He takes him under his wing, teaches him, shows him the ropes. He grows up, badda-boom badda-bing! He gets his revenge. End of story.

3. "They don't need Goodkat until..."

A. They don't need him until a job like this comes along. Were you not paying attention to the film? You know, at the begining of the movie, where they say they hire him to do the jobs nobody else wants. Thought that might have been a dead givaway. I see that people's powers of perception are failing, as always.

There is nothing far-fethced about it at all. If people actually pay atention and interpret the film properly, you'll see there are not "plot holes", such as the afformentioned. Just lousy viewers.
