scarface is better on many levels.
-Blow throws a bubbly cute hollywood blanket (over an awesome story) but in return making it hard to really captivate me to give two fucks about the characters struggle.
-Compare soundtracks.
-Tony Moñtana's sister > penelope cruz imo.
-Scarface transports you to a certain time/feeling/pace while Blow feels like just another movie that could of been set anywhere. The 60's californa setting almost had the same feel as columbia, come on now!?!
-Raw emotion, struggle, the fight and drive, etc is more realistic in Scarface.
-Scarface's ending fight scene >
Blow does have wacky ass Pee Wee Herman in it (kudos) but personally to me Scarface is the superior movie.
