Foster's, personally, takes a specific frame of mind to actually watch and enjoy. The same with Johnny Test. It takes a certain mood to watch it, otherwise it's irritating. I was surprised when my brother said that he watched it and liked it, til he explained that he has to be in the mood for cornball Flash-animated screwiness.
Though, I saw someone knocking Ben 10. I'm rather critical of cartoons nowadays, but I rather like Ben 10. It's a good action romp and the style is tolerable. I've been only recently watching it, as it's on after Clone Wars. Same with The Secret Saturdays, since it's on before Clone Wars. It's a good action romp, the characters aren't irritating, and the style is tolerable. I'd rather they revisit the detailed style of cartoons back in the Golden Era, but with how cartoons seem to be taking a shot to the head as it is, I'll take what I can get in terms of just plain decent programming.
Perhaps some distant day, we'll see a return of the animation Golden Era. Until then, animators need to get their acts together. If detailed, decent plotlines can make a comeback, perhaps detailed decent animation will follow suit. It worked for Chaotix. The animation style used to be crap, now it's half-decent. Not sure about the plotlines as I don't watch it regularly, but I did notice a change in animation style. And then there's Biker Mice from Mars, drawn in the original style as when it first premiered back in the 90s! Seeing that gave me hope that perhaps we were seeing a resurgence of the Golden Era.
...Til I read that Fox is nixing its Saturday Morning programming. Now, may whatever diety have mercy on their souls, as if I were any where within arms' length of the Evil Network Executive, I will have them in thumbscrews. Then exterminate them.
