I've had rather mixed feelings about this episode. To me, its not the type of episode you can watch again and again and yet enjoy it. Its kind of funny, it does have some great moments but it kind of got quiet towards the end. However, I did love the Mars scene and the parents reaction to losing Max in Mars.
This episode also teaches you that parents may not always do what you want, but they do it for good cause. That's the great part about this episode. It clearly illustrates this very well.
It certainly is a good episode for a laugh!
