I have an interesting dilemma.
My wife is sick of the Pixar/Disney/'kid' movie staples we've been rotating in our house for the past few years and would like to watch something that's not pitched straight at the 'kid' audience. She also is pretty clear that she doesn't want inappropriate sexual situations peppered into our choices (as we found out as we got into season 3 of Buffy).
Some winners have been:
Doctor Who (2005 reboot through Season 5) - our kid is a big fan
Groundhog Day
Harvey
Enemy Mine
Starman
Little Shop of Horrors
Romancing the Stone
Contact
The Karate Kid (original) - a ‘kid’ movie that held up well when watched again as a parent
Peter Pan (2003) - a 'kid' movie with wonderfully complex themes - family favorite
Some shows that we're considering, but aren't sure about:
Highlander TV Series (we enjoyed it, but aren't sure if it's too 'romance novel' for our 11yo)
Star Trek (Original) - seems like a good pick as morality plays, but I haven't watched in years and am not sure how much of Kirk's horn-dogging was going on.
Twilight Zone - Probably a good pick, but might be a bit adult and scary
Do the teeming millions have any suggestions? If you want not aimed at kids, but no sexual situations, you need to look into things aimed at teen+ viewers, not kid or the 18-32 demographic. So... Check out the first few episodes of Instant Star and Being Eve. The former is about a teenager who wins a contest like American Idol, the latter about a quirky teenage girl telling people about her life. I was in my early 20s by the time I discovered either and I liked them a lot. It looks like Eerie, Indiana might be available too, and I even got my parents to watch it back in the day.
I wish they offered Strange Days at Blake Holsey High, and So Weird, but they don't. Strange Days is often on Discovery Kids, though. I'm still waiting a decade later for So Weird to ever be shown again
