Because most plots in anime are a hell of a lot better than that of regular shows. u can only go so far with a plot in a regular televisie toon but with anime it's endless! u can make the characters do literally anything u want them too. Especially with weapons and fighting. Plus u just can't get the same reaction with a classic anime blush of shock expression! =] Oh yeah and as for cartoons...there's just no true substance. There's really no theme to them. I need something with a purpose not just a bunch of common funny words thrown together to make me laugh (which it never does) and hope it gets popular.
I mean come on! Do u think u can get these types of faces in real life XD!
I watch anime because i think its better than American cartoons, i mean each anime is different from one another, and each one is unique, i just think anime is meer unique and different than normal cartoons.
