Having seen both the director's cut and the original, the original is definetely the better one. However, I don't hate the DC as much as I hate the SE's of the Star Wars series. THX-1138 was a very low budget film, so I can agree with him on most points that they simply did not have the money to do certain things. The editing feels very cramped in a way that I can feel that they desperately wanted to pan over to other things, but couldnt' for fear of exposing the small sets.

So, originals the best, but I recommend checking out the DC as well.

BTW Trooperman, the "eye-rolling" scene is something you'd need to see the DC to understand. He is not simply rolling back his eyes like we would, they roll back completely into his head, something they could not have accomplished simply with the actor as well as their effects budget. Is it an improvement though? In the case of the scene, I feel it helps, yes, but its nothing earth shattering.
