I think Tarantino is better than Rodriguez in everyway film making-wise!
I think QT’s dialogue is much better (witty, poetic, natural). Rodriguez asks QT for advice when writing dialogue, this basically tells all. I also think the way QT films is also better. QT has some really cool shots in his films and sometimes the camera placement in RR’s films can become borring. (Am I right in saying the scenes Rodriguez directed in Pulp Fiction were also quite plain and boring?) Don’t get me wrong, Rodriguez is a brilliant director, and I like his style, I just prefer QT. I also prefer the characters QT thinks up rather than those that RR does. I like the fact that there is quite a bit of Leone in RR’s work, obviously he is a big fan (like QT). RR also uses some great music in his work, it just seems that RR experiments a bit too much now in his films and his style is always changing. I think he is just having fun with all the new technology.
One aspect I feel RR is better is in terms of making music. I think Rodriguez is a fuckin brilliant composer, his music from his own films and Kill Bill were breathtaking.
I seriously think Quentin Tarantino and Robert Rodriguez can become the new Sergio Leone and Ennio Morricone. I hope RR scores Inglorious Bastards (seen as it will be QT’s spaghetti western, and RR can make some good Spaghetti western-type music).
