This is so close to being the kind of roadtrip/coming of age film I have a soft spot for, it's almost maddening. All it would take is removing some of the dull, family-friendly touches and making smarter casting decisions.
This shouldn't be scary anymore because of the way the effects have aged, but it still got under my skin. Probably because of the curse associated with the filming? Plus that f#cking clown doll. But at the end of the day, Poltergeist is just a really beautifully made movie. The final shot, for example, is a perfect ending.
