Ni hao Jay , Yes it could be one of the methods you can use to learn English ,but wouldn't be effective on its own without practice . When you watch a movie you are already having fun , so it is an entertaining way of acquiring new vocabulary and getting hold of the accent by listening .

I would say, it depends on the person. But, as an English tutor learning a language by watching movies isn't a good way to learn. Why? Most Hollywood movies use SLANG words which is not good for people who are beginning to learn a language. They think that it's "cool" to use and oftentimes, they don't know the meaning and the intensity of what they are saying. If for entertainment purposes, it's OK. But, if you serious in learning start from the very basic: reading, listening, writing and speaking (practice these regularly) then try watching movies and see how far you can understand.

Many Chinese have told me they learn a lot of English by watching TV. The grammar and usage is USUALLY pretty good. However, the slang can depend upon the type of show. Also, if you are thinking life in the United States is like the shows you watch, that is probably NOT true. That is Hllywood NOT America.

hi , i agree with u , it also may help u to improve ur listening skills , ofcourse u will interest in other ways to improve ur english ( reading , grammer , etc...) good luck.

i think if you want to learn english first you have to start by listening it...for this you can see English program on tv and try to listen and understand. May be in starting you will not get it but sure doing this regularlly you will start understand, after this you should start speak it...and at last you can do writing exersice. like how we learn our native language after birth we listen our parents and then started talking and after going school we learn how to write it. Same process we have to do for learn any language. :-)
