Sad more than scary (SPOILERS)
I finally was able to watch this movie after hearing about it two years ago. It did have some spooky moments, but I found this to be more sad than scary.
I say this because Andy comes home to a family that seems to truly love him as a family should and is unfortunately a zombie/vampire instead of the loving child that he was before going to war. Also, the outcome of involving the girl who went with him on the driven-in date was sad as well because she still seemed to be in love with him and he..well, does what he does to her in the movie.
His sister loved him so much she tried to set him up with the old gf -- his mother loved him so much she wished him back (although it might have been better to let him rest in peace, as i think is the whole point of the "Monkey's Paw" aspect) -- his father loved him so much that despite the dog incident, etc, he lies to police to cover up for him -- also the mailman, etc...
But sadly, Andy is not the same as he was.
Finally, the final scene in the graveyard is the saddest of all.
It is sad to think that many went off to Vietnam and came back , not as scary zombies, but as changed people. (Also, I believe the blood injections symbolized the drug additions that some Vietnam vets had when they came back). It is also sad to think the same is most likely happening for those who are coming back from Iraq/Afghanistan.
Sad, yes, but a good movie. I hope they don't screw it up with the remake.
