You know you're old when you saw in a theater, or at least remember, the original movies when the remakes come out.
The Poltergeist remake opens on May 22, 2015. IIRC, the 1982 original was rated "PG", and caught some heat afterward for being too intense for that rating. Gremlins two years later also got a "PG" rating, and took the same heat. That led to the "PG-13" rating. Which most movies today seem to strive for.
The running time on the Poltergeist remake is about 95 minutes. That's about 30 minutes shorter than the '82 original.

Not a bad remake, IMO.
