This show is many things all at once. It is funny, yet deep. There are tons of people getting smacked in the face, but every once in a while, there is an epic story to go with some episodes. It also occasionally has guest stars! This show is like a modernized Three Stooges show, but with younger people, and a lot of profanity.
There are some episodes that are action packed, and are filled with aliens, monsters, the mafia, or their arch nemesis, Doctor Mac. He is the one who all the members of The Marvelous M are trying to defeat whenever he tries to destroy them. There are also aliens that they have to battle, space odysseys, and there are tons of lessons that can be learned from this show.
This show occasionally also makes parodies and makes fun of many things. The parodies and jokes are very well done. They are sometimes faithful to the source material, but can always deliver a good punch line.
They often do requests from viewers, and that is one of the reasons why many people watch this show. They've done requests on science fiction, fantasy, pop culture, and even reenacting life situations that people have gone through.
The main thing that many people watch this show for, is the slapstick comedy. There are people being hit left and right. In the face, in the groin, on the top of the head, poked in the eyes, almost every episode has at least one person who gets smacked in the face. It is done very well and is very entertaining to watch.
Overall, this is a great show, and I highly recommend it to everyone.
