The book is a good read. The real Tommy was far more deranged than in the movie. Goodfellas substantially polishes the characters, who were generally drug addicts and degenerates of the highest order. One of the most popular true crime Mafia books is Murder Machine. It's never been made into a movie, because it would essentially be 3 hours of low IQ psychopaths torturing and murdering people for little to no reason. This isn't just a Mafia thing either.
After the success of Chopper (which demystified organised crime to a degree) we got the Australian film Animal Kingdom, based on a real Melbourne crime family. The movie had a good cast, some Oscar noms, and was very good in general.
But even in that case the director deleted a lot of scenes and altered the story because he said people wanted to see a crime movie, not Wolf Creek. The real life family were like the freaks from a Texas Chainsaw Massacre movie who happened to fall into assloads of money because of heroin trafficking.
