I really love Crayon Shin-chan. I don't think I can get tired of that.
Haha, it's impossible to get bored of that character, very comical, daring and insightful.
On the other hand, I perfectly understand what you say and share regarding current anime, in my case the same thing happens, that's why I don't watch anime from this time.
But if you want to watch anime, I recommend watching old series that you haven't seen or liked as a kid. Back then we tend to miss important details of their story more than anything else, so watching them again will give us another perspective, plus it's a moment of entertainment.
Yeah it does seem like the older creations will be more appealing, as they were even before. Despite trying to find new shows on MAL, I find I end up just getting lost in a sea of things that are just definitely not for me.
