I just bought the long version a few days ago, and it's definetly ten thousand times better than the "Director's Cut" I got a long, long time ago. First movie on DVD I ever bought to stretch over several DVDs

.
I full-heartedly recommend that whoever wants to buy this movie gets the longer version. The Director's Cut is for the Hollywood movie-lovers, as it focuses on the fighting. The long version keeps nearly everything (my copy is 4 hours 42 minutes long, wasn't the original TV series 6 hours long

?).
So now I guess I'm off to sell the short Hollywood-ish version. Who needs it anymore!
