I highly recommend the Rocket Japanese course.
I'm a Brazilian living in London. So I'm learning a foreign language in English, which is not my native language in the first place. But I'm really enjoying, the content is very clear and easy to understand.
I've seen some other reviews complaining about the "new" Kenny, but I must say I prefer the new one. The fact that he is native helps a lot, even without the whole "enthusiasm" the former one had.
I started last year and had to stop for a while as I didn't have time to continue, but now I've started over and noticed the new narrator and new Kenny as well. I found a good surprise.
