1.Road to Perdition (2002) - 10/10 (within my Top 10 movies in general simply because there are only ten movies i gave a 10/10 score. it's a underrated masterpiece.)

2.Once Upon a Time in America (1984) - 8/10 (within my Top 61 movies)

3.The Godfather Part III (1990) - 7.5-8/10 (within my Top 109 movies)

--.American Gangster (2007)
--.A Bronx Tale (1993)

13.State of Grace (1990) - 6/10 (closer to a 5.5 than a 6.5) (needs a re-watch though as i think i have only seen it once so far and that was sometime before Dec 27th 2011. but currently i like it.)

14.Goodfellas (1990) - 5/10 (Thumbs Down)
--.Miller's Crossing (1990)
--.The Untouchables (1987)

NOTE: anything i score a 6.5-7/10 or higher is amongst My Favorite Movies which includes 199 movies.

p.s. i was debating between The Godfather Part III/Casino for my 3rd spot(as they are roughly tied for me), but ill give GF3 the edge for now. especially since i expect Casino to have more votes between the two and GF3 could use a bit of a boost.
