In my opinion, this is the best sitcom ever! I love how every character is unique and funny. Rachel and Joey are my personal favorites but the rest are really great as well. My whole family has watched the entire show at least 50 times, and they all love it. Friends is just as fun to watch the first time, as it is the last. All of the seasons of the show are amazing. Me and my brother started watching the show when we were 10 years old, so i think it is perfectly fine for kids of that age to be watching it. Yes, it may have a few inappropriate scenes here and there, but most of it is pretty family friendly.
Overall, this show has got good humor, good characters, and is very iconic. I highly suggest watching it, especially to people who like sitcoms.
