YMMV: Marvin Marvin
- Squick: Marvin, among other things, vomiting cereal.
- Tainted by the Preview: Let's just say that if you were already annoyed by Fred, the announcement of this show was this.
- The Scrappy: It's yet another show where the main character is this, due to Marvin basically being the same character as Fred sans the squeaky voice. Nickelodeon seems to be on a roll with this trope, with a lone exception.
- They Copied It, So It Sucks: Many viewers accused this show for ripping off Mork and Mindy, My Favorite Martian, and other assorted sci-fi comedies, not to mention Marvin the Martian.
- Uncanny Valley: Marvin's alien form, not helped at all by the Conspicuous CGI.
