My thirteen year old daughter began tuning into this old series after watching an episode with her dad. I watched a few prior to letting her continue to view them. My main concern was that they're pretty violent. There always seems to be a murder, gunshot wound, etc. It's sometimes peppered with a bit of colorful language, but I wasn't overly offended. It's very much a futuristic sci-fi show and that's the sole reason I've given it the go-ahead, despite the violence. It's not remotely realistic and I think a teen can easily discern that. Thankfully there were only a few seasons made!
