I won't repeat what others have already sad. The thing that stands out to me is that the reworked plot works better. In this version, each tragedy causes the next, like a runaway train. Once they move to the new house, the events are inevitable. Having the girl get killed rather than the toddler allows for way more dark, complex and creepy situations.
The evil of the burial ground is more palpable, and you get the feeling that the people are being influenced by the Wendigo. The same goes with Rachael's vision of Zelda. In the original, they were just flashbacks to provide backstory, but here the visions start as soon as they move to the new house (she even says so), and she is more like haunted by Zelda, via the Wendigo.
