This is a great show. I'm on season 3 and so far at the end of every episode there is something positive said. YES, there is lots of sexual relationships, but if you understand what it is, I don't see what the big deal is, but that depends on the person. It's very educating, you learn a lot, and for anyone who's thinking of going into anything medical, this is great! You can learn a lot more about the medical field, etc. it's overall a very great show, and fine for a teenager, as long as your mature and understand what's going on. ALSO there's lots of blood (you see surgeries), so if your sensitive towards that, Greys may not be the best show for you.
