Entourage is a great blend of comedy and drama. It has a very interesting storyline and has great character development. It is pretty much an R-Rated movie, and most older teens are allowed to watch R-rated movies anyways. The language in Entourage can be harsh at times, but nothing too over the top. Sexual content can be an issue in some episodes, but most sexual content is implied. For example, a character might pick up a hooker and go to his room for you know what, but nothing is shown. However, some episodes may feature nudity which can be graphic. but that is very rare. Overall. Entourage is suitable for older teens 15+. It can be awkward to watch with your parents, but teens should be able to handle this. There is nothing in this show that your teen has not been exposed to or seen before. My sons watched this show when they were 15 and 17, and they felt that while it can be mature at times, overall it is a great show from the hit-making HBO channel. Mature teens who have watched R-Rated movies should be fine with this series. Nothing too explicit, or over the top. The only reason the show is TV-MA (equal to Rated R movies), is because it is on a private channel (HBO). Shows on FOX and NBC could easily be TV-MA if they were on private channels, not public.
