I can tolerate Poof. It was annoying how many times he was addressed as the greatest thing ever and ccould pretty much do anything despite being a toddler (a fairy, but a toddler nevertheless) to pretty much Gary Stu levels. However, his debut episode was decent to me and with time, those adressings to him kinda vanished, now he's just there, so I don't find annoying anymore.
HOWEVER, that too is a problem. He does almost nothing, he's just there to provide a baby joke or two and that's it. You can't add a main character that does nothing, it's boring.
It finally put the final nail in the coffin with Sparky's inclusion making me go away as far as possible. And now Chloe.
I do know why the show is still airing, but that doesn't makes it any less of a bad show that already passed it's prime.
