My teen-aged boys and their teen-aged cousins enjoyed it, along with their parents and grandmother. It depends on the teenager, I suppose. Some think everything is childish, others are grown-up enough to like being childish sometimes.
We played is as a group of 9, which probably made it more difficult because we were enjoying watching the kids enjoy it, and thus not paying attention TOO hard, and sometimes it was hard to see past each other, but it wasn't completely simple. In fact, at one point, doing the Muppet one, we had crossed off ALL of the suspects, so we had to back-track a bit to find a clue where we had inadvertently ruled out too many suspects.
It is a great way to "tour" the ship, and I liked that there was a little activity at each station, not just a "go here, go there" type of thing. I also liked that you could start and save multiple adventures at once, in case you were doing it with different groups of people, and that they had three separate "cases."
