You have to give Disney credit for trying something completely new with Phantom Manor. After going on WDW Haunted Mansion I thought to myself "I could have done that at home".
After watching every video I could find on You Tube, Phantom Manor intrigues me. In fact, the original tape with Vincent Price was, pardon the pun, Priceless.
Sometimes I prefer storylines that leave a little to the imagination like HM and POTC. For that I give my vote to nostalgia. Either way though, if any more Parks are created with another Mansion I'd love to see something totally unique like PM and less cookie cutters like WDW.
