HM is one of my favourite rides, no question. But I have to say, having ridden it and its DLR counterpart only a couple months apart, that DLRs ride is better. Not the queue, of course. The graveyard scene in particular stood out to me.
Having said that, I think that Disney's best rides are the ones where the Imagineers were allowed or encouraged to come up with original attractions not deeply tied to movies. HM, POTC, BTMRR, Splash, SM, EE, ToT. Of course Radiator Springs and Indiana Jones at DLR are notable exceptions where the Imagineers really went all out. I'd dearly love to see them get back to doing their innovative best at WDW.
