RUSH is a good movie. It's a great story, told very well. The acting was good and the direction was fantastic. I'm an F1 nut, so perhaps I'm a little biased, but looking at RUSH as a movie, it stands up and non-F1 fans can enjoy it if you don't go in thinking this is another racing movie.
I've been a fan of Ron Howard's work, but it has been a little uneven. APOLLO 13 is a great movie. A masterpiece. I really like BACKDRAFT, but it's not the same as APOLLO 13. I'd put RUSH about on par with BACKDRAFT. It's that good.
