I grew with the original back in the day and I gotta say I don't know what to make of the new trailer. On one hand , I think if you're gonna remake a classic like Fright Night you've got to go in a different direction which looks like this version is. Clearly they've updated the story. On the other hand, why call it fright night? Fright Night is creepy but it was a bit of a satire and funny as well. If anything , Scream 4 is closer to the original Fright Night then this is from the trailers at least. But who knows.
It seems to me the problem with alot of these 80's remakes seem to be that alot of the 80's films worked best in the context of that time, and these film makers today try to bring a 2000's ironic and snarky sense to stories which fit best in the 80's. Hollywood isn't moving toward some of the stories whose elements are timeless. They are instead going alot of the dated pop culture classics like A Team, Athur, Robocop, Smurfs etc. Then when the remakes fall flat with the audiences the studios don't seem to know why.
