Why should i look anime ?

Hello there,
Let me share my thoughts on that by asking you this:
Why are you watching movies, play games, or check videos on Youtube?

It all boils down to whether you find it enjoyable or not.And there are many factors to that:from animation to plot.And there are respective parts in every media(in movies for example, animation=actor interpretation and plot=scenario)

It's not that it's cartoon,basically "anime" stands for "animated".There as are the sames genres you would find in the movie industry.
I would suggest giving it a shot,to check if you like the easthetic/culture/Japanese culture, and see where you go from there.

Or not,it's not like someone will stone you for not being interested or curious.You do you.
