I don't have a problem with the fact that they're lesbians or anything, but this just looks like a really lame show. I mean, okay, so it's a kid with lesbian parents, and.. how exactly is this supposed to be an interesting show? Judging from this preview, apart from making it clear that they're lesbians, they're sort of glossing over anything they could do with that storywise, and otherwise it looks like a very boring kids' show. I can't see any kids watching this and thinking "wow, I wanna watch that!"
To me, it almost seems like the whole show is designed to be as bland as possible apart from the lesbian aspect, so that kids associate lesbians with "normal; nothing to get excited about". Which would be a fine idea, if they weren't wasting lots of people's time and money creating an unappealing show in the process.
