Both movies had similar plots but GoNY went about it the right way. No one would have predicted Amsterdam getting so close to Bill the butcher to the point where it was so difficult to kill him. Most if not everyone would of predicted both of the gangs to fight in an all out gory scene in the end, but instead Scorcese made quick work of that and did something else much more unlike the norm which made it less entertaining but a better movie all in all (above post).
