When I first saw this after it came out, I had no idea who Guillermo Del Toro was, but I could tell that the director knew what they were doing. Although the plot is a little silly, the direction is handled masterfully, making for an entertaining and sometimes frightening experience. The bluray transfer really brings out the beauty in some of the shots.
I hadn't seen this movie in years until i recently bought the bluray. It's every bit as brooding and strange as I remembered, but if you look for it you'll find that it also has a sense of humor about it itself, which i appreciate. The bluray quality greatly improves the at-home viewing experience as well.
Poltergeist is one of those classic horror movies that sticks with you. I still remember the first time I saw it when I was a kid, then begged my mom to buy me the VHS. The quality of the bluray makes for a whole new experience!
