While I agree for the most part that most remakes suck we can't forget a few remakes that didn't: Dawn of the Dead, The Ring, The Fly, The Thing. I would add a few more, but I've had a long and damn tiring day and I'll be danged if I can think too straight, so I'll try not to stray too far off the beaten path with a list.
From the looks of the trailer, it seems like it will be a fairly decent flick. It's atmospheric and it looks like it will go more in depth with the incident that happened before the Lutzes moved in. The first film with Margot Kidder and James Brolin left me sort of cold. They were too old for the roles and I defy ANYONE to point me in the direction of a single film in which Kidder was even remotely attractive. The Superman movies don't count, because she looked like a tired, washed-out drug addict in all those films. Kathy Lutz was pretty, young and blonde and I believe that Melissa George was born to play the role (like Rachel MacAdams should have been cast to play Susan Storm in the upcoming Fantastic Four movie until they gave it to Jessica Alba, but that is material for another thread.) Ryan Reynolds is a likable enough actor and it will be interesting to see if you feel more for his portrayal of the Lutz patriarch than that of Brolin's dull outing.
Overall it might be worth seeing in the theater, but I'm firm in my belief that most haunted house movies are boring as hell. Spaulding will really step on me hard for this one, but one of his favorite films, The Haunting (1963), was one of the biggest cinematic snoozefests of all-time, IMHO.
