• This show isn't bad, but why did it have to be a sitcom? I like TV shows with science fiction, and I notice that most science fiction TV shows on Nickelodeon are sitcoms. Marvin, Marvin is considered one. There's another one coming called the Thundermans. Why do all Sci-fi TV shows on Nick have to be sitcoms? Nick can do much better than that. I wouldn't mind if they made a Sci-fi show that's not a sitcom. Nick needs more Sci-fi shows that are not sitcoms. I'm just saying, it will probably get more viewers if it starts doing that. I'm not saying the show is bad though. I really like it and it is quite creative, but no one said it had to be a sitcom. People would still like it if it wasn't one.
