Martin Scorsese's masterpiece features a lot of unlikable characters and snitching wise guys. But Tommy DeVito was so menacing he managed to play antagonist to even the bullies and murderers that trusted him. Joe Pesci's brings this character to life and gradually builds fear from its basest element, since in plain view Tommy Devito is short, goofy looking and has the voice of an Italian clown. Few actors could make such an under whelming presence into a modern monster.
I'll never get tired of watching Goodfellas; the entertainment value of this film is just amazing. It doesn't happen very often that every person involved in the process of making a film is at the peak of his/her game. And rarely do art and entertainment come together the way they did here. Storytelling with impeccable pacing, this is what it's like when a master composer conducts his masterpiece. All hail the king; the most versatile and talented filmmaker of his generation: Martin Scorsese
