I say to try and stay away from Japanese media until you have mastered the basics of grammar, and have a fair amount of vocabulary.
It`s much much easier to gain something if you understand the pattern the new word is appearing in, or if you understand a number of the words in a new pattern. Otherwise, you`re simply going to be confused and end up with more frustration than anything else.
It also tends to make people give up far earlier than they should, as it can be very humbling to watch something aimed at kindergartners and not understand more than two words.

Once you *do* have those basic patterns down though, it can be a great confidence booster.
