Most Helpful Guy
For learning English? It was also my second language though I started when I was quite young.
I really think shows and films targeted at children can help a lot, since they speak very clear, simple English.
My childhood favorite shows in the U. S. when I was learning English were Inspector Gadget, The Mysterious Cities of Gold, and Adventures of the Little Koala. They might be a bit dull for an adult but might be quite clear and easy to understand. Disney films were also nice for helping me to learn.
