Re: JFK & Amadeus - Holding Off Purchase Until ...
I agree: longer isn't necessarily better. Neither is shorter, although those are the rarer DC's. To me it depends on what's put in or taken out. Also, it's quite possible that the filmmakers never want the theatrical cut seen again after they get their "preferred" version out. In the case of both Amadeus and JFK, I happen to prefer the Director Cuts, but many people don't. I think they both help flesh out important points.
More so in the case of JFK, where some dialogue in the Theatrical Cut makes no sense until you see the DC. For instance, the scene where Costner wakes up Spacek and says Bobby Kennedy's been shot. And she replies, "You were right!" The implication in the TC cut is he was right about the JFK assassination theory, which is all she had doubted him on. But it makes no sense that the killing of Bobby Kennedy would make her change her mind about the unrelated JFK killing. In the DC cut you see him predict Bobby Kennedy's assassination and
that's what she is replying to. Now in the DC it makes perfect sense.
