This show isn't TERRIBLE, but it seems like it copies most of the sitcoms that have been popular lately.
The fact that the four main characters are all quadruplets is unique, I guess, and it's easy to pick a favorite (Nicky, of course B))
Nickelodeon is still the worst kids' channel on television, with Disney close behind. But their shows have improved a TINY bit since Breadwinners. Maybe TV is making a comeback.
Anyway, back to the show. The characters are quirky, and the teacher is HILARIOUS. It's a show that appeals to both boys AND girls, which isn't something that you see a lot nowadays (most TV sitcoms nowadays are geared towards girls) and it's not painfully bad like The Thundermans.
Overall, I'd say this show is somewhat worth watching.
