By the time I turned fourteen, I had seen all three Star Wars movies, Back to the Future, Short Circuit, Grease, Superman, Superman II, WarGames, Romancing the Stone, Indiana Jones and the Temple of Doom, Flash Gordon, and probably a few more movies the names of which escape me at the moment. My family didn't go to movies much, that I can recall, but I saw them in trips with my summer camp, or at birthday parties.
I won't deny that listing those titles brings twinges of nostalgia, but I can't see showing those to my kids.
First, there is the halachic issue of looking at certain things. The Torah warns us not to stray after our eyes, and that includes having a male see a female in states of undress. Even back in the sheltered 1980's, what passed for a PG in the theater would not Please Gd in halachah. This one is pretty straightforward.
More, though – Even if you could skip any given scene, a teenage boy is going to face enough of a challenge dealing with his sexuality within the bounds of halachah; do we need to feed it by promoting a world in which it's all around him, a world of strapless dresses and bathing suits, a world of jokes about appearances and sexuality, a world in which the music swells as the characters kiss?
Nope; I don't see it.
