Mickey is somewhat missing the point in that Lee's primary motivation is not one but two personal agendas. Han is a murdering, drug dealing slaver, so it's pretty hard to paint him as a victim. I think Mickey is yanking our chains.
OK, flame retardant suit on, Enter the Dragon is a BAD MOVIE. The plot is weak, the direction is terrible, the dialogue is attrocious, only half a dozen people in the entire film can fight. I need to be drunk and nostalgic to even watch it these days, and I certainly wouldn't recommend it to ANYONE as an introduction to martial arts cinema. The entire film is carried by Lee, his back injury must have been really playing up.
However, the basic concept does have some merit, and as such a reinvisioning could be good. This looks like it will be FAR from a straight remake, so I think we should wait and see, it could have some promise.
