What Anime Teachers That Is Wrong

[Jennermack 0]

Hi,

One of my big motivations to learn Japanese is so I don't have to be distracted by subtitles when watching subbed anime.And I have heard on this site and many others that we should not use anime as a teaching tool because many of the words are not used in real life conversation. Well, I know that no one is going to yell out Kamehameha or any of the other battle cries or attack names that frequent anime. So other than that, what commonly use anime words or phrases are not really used?
I here the word Kimi ("you" from what I understand) a lot in both anime and JPop and I have heard that no one really uses it in real life.

Any help will be apprecited.

I didn't find the right solution from the Internet.
